cc158e7009 Swapped the order of two conditions in an assert. (#4663)
An assert in flexbuffers was bit-shifting a 64-bit number by
64 bits, which throws up warnings in some automated tools.

The same assert also checks to see if the number of bytes
being shifted is 8.  Swapped the order, so that the bitshift
only occurs if the number of bits being shifted is not 64.

Should be the same behavior, but plays nicer with diagnostic
tools.

77b458bee5 Make nested flatbuffer lookup consistent. (#4656)
Lookup type of nested flatbuffer field with either raw name or fully qualified name as already done in the parser.
LookupCreateStruct tries both the raw name and the fully qualified one.
Without this, we cannot reference types outside of the current namespace, e.g. in a different module.

b24c0b07a3 When Java raises a CharacterCodingException, the catch block rethrows this exception as a java.lang.Error. Per the docs https://docs.oracle.com/javase/8/docs/api/java/lang/Error.html an Error is a serious problem that applications should not attempt to catch such as ThreadDeath. In this case, it is reasonable for a consumer to try to catch this error as it likely indicates a problem with the underlying data. (#4630)
As Error does not inherit from Exception, a generic `catch(Exception ex)` will not catch this error.

A simple change from `Error` to `Exception` is not sufficient as an `Exception` is checked by the compiler, so in order to keep this issue unchecked, I am proposing raising a `RuntimeException` which is not checked, but is still a subclass of `Exception`.

The only possible breaking change would be if a consumer was explicitly catching `Error` already for this library.

36f8564846 C++: mini_reflect: Add DefaultTypeTable (#4614)
* mini_reflect: Add DefaultTypeTable

Currently it's very easy to make a mistake when it comes to
instantiating the TypeTable to print a buffer because it is not type
safe.

This will allow us to write safer cpp code:

flatbuffers::FlatBufferToString(reinterpret_cast<const uint8_t *>(&t),
                                decltype(t)::DefaultTypeTable());

* Ensure types and names are set for mini_reflect

* c++: mini_refelct: update unit tests with new typed TypeTable

79b80f84df Reduced FlatBufferBuilder from 3 buffers to 1
Previously, FlatBufferBuilder used 3 resizable buffers:
- serialization (vector_downward)
- field offsets (std::vector)
- vtable offsets (std::vector)

Since the serialization buffer grows downwards, the bottom part of
it can be used as a "scratchpad" storage for the other two. Since
field offsets are only accumulated during table construction, and
vtable offsets only after table construction, the two can trivially
share the same storage.

Not only does this reduce the amount of allocation, it also removes

dfe68566e4 Add char * overload for FlatBufferBuilder::CreateString() (#4583)
Without this change, the compiler tries to select the following overload
when CreateString is passed a `char *`:

    template<typename T>
    Offset<String> CreateString(const T &str) {
      return CreateString(str.c_str(), str.length());
    }

which is not valid since char pointers don't have methods.

(Fixes #4579)

0c8b4c7614 Add support for Python lib continuous deployment.
Use a combination of travis and twine to publish to PyPI. New
publications will be made:

* When `master` is updated. This will trigger the publication of a
  the Python artifact versioned an iso-compliant build datetime. In this
  way, the cutting edge version will always be available via PyPI.
* When a new git tag is pushed. Tag pushes trigger the publication of
  a python artifact with the same version as the git tag, with the
  leading `v` stripped if present (`v1.2.3` becomes `1.2.3`).

Publications rely on Travis having a PYPI_PASSWORD environment set in
the project settings. See the Travis CI documentation for information on
[setting environment variables which containing sensitive data][1]. Make
extra sure the "Display value in build log" switch is OFF.

In addition to setting the previously mentioned `PYPI_PASSWORD`
environment variable, the owner of the PyPI `flatbuffers` repository
should, after merging this commit into master, add his own commit to
change `mikeholler` in `.travis/deploy-python.sh` to his username. It's
also recommended that the owner of `flatbuffers` use a separate account
in the unlikely event that the environment variable somehow becomes
compromised. Again, this is very unlikely, since the environment
variable is only set for "safe" builds approved by maintainers (not on
random pull requests).

Clang complains
call to function 'EndianSwap' that is neither visible in the template definition nor found by argument-dependent lookup

This seems to be due to limitation of two-phase lookup of dependent names in template definitions

Its not being found using associated namespaces therefore
it has to be made visible at the template definition site as well

C++98 (stlport) support for core FlatBuffers and FlexBuffers.
2017-07-20 12:24:38 -07:00
Stewart Miles
a892322203 C++98 (stlport) support for core FlatBuffers and FlexBuffers.
* Added internal - limited - implementation of flatbuffers::unique_ptr
  for STLs that don't ship with std::unique_ptr.  In C++11 and beyond
  this is just an alias for std::unique_ptr.
* Aliased used type traits structs is_scalar is_floating_point is_unsigned
  into flatbuffers namespace so they can be replaced in C++98 implementations.
  Right now these point at stlport's TR1 implementations.
* Wrapped vector::data() in vector_data().
* Wrapped vector::emplace_back() in vector_emplace_back().
* Wrapper string::back() in string_back().
* Added variants of FlatBufferBuilder::CreateVector() and
  FlatBufferBuilder::CreateVectorOfStructs() that allow the use of plain
  function pointers.
  Generated code has also been modified to use plain functions to build objects
  rather than std::function() so all generated code will work in C++98
  applications.
* Added flexbuffers::Builder::Vector(), flexbuffers::Builder::TypedVector()
  and flexbuffers::Builder::Map() methods that allow the use of plain function
  pointers.
* Changed Parser to internally use plain function pointers when parsing table
  and vector delimiters.
* Added specializations of NumToString() for 64-bit types that aren't supported
  by stringstream in stlport.
* Overloaded numeric_limits for 64-bit types not supported by stlport.
* Replaced build_apk.sh (which was broken by deprecation of the
  "android" tool in the Android SDK) with build.gradle and the
  appropriate gradle wrapper to build an APK.
* Switched Android build to build against all STL variants.
* Updated travis configuration to build Android test and sample.

Tested:
* Verified all tests continue to work on Linux, OSX and Android.
* Verified Travis build is green.

da67c0a71f [C++] Improve flatbuffers + gRPC integration (#4310)
* Rework flatbuffers + gRPC integration

- Introduce `flatbuffers::grpc::Message<T>`, a `grpc_slice`-backed
message buffer that handles refcounting and allows flatbuffers to
transfer ownership to gRPC efficiently. This replaces
`flatbuffers::BufferRef<T>`, which required a copy call and was also
unsafe w.r.t. buffer lifetime.
- Introduce `flatbuffers::grpc::MessageBuilder`, a gRPC-specific builder
that forces a `grpc_slice`-backed allocator and also adds some helpful
`Message<T>`-related methods.
- Update serializers accordingly (now zero-copy between flatbuffers and
gRPC).

* gRPC: verify messages by default, but allow user to override

* gRPC: fix some formatting issues

* Disable verification by default, but add helper method

* Make FlatBufferBuilder fields protected + remove vec accessor

* Use bool add_ref parameter to toggle refcount incr

* Remove unnecessary inline specifiers

* Fix formatting

* Use auto

* Remove empty lines

* Use grpc_slice helper macros

* Simplify reset code

* Disable Message copy ctor and assignment by default

* Remove unused member

* Enable gRPC verification by default

* Bake in message verification (remove template specialization)

* Add RoundUp func

* Consolidate gRPC message copy flag

* Make vector_downward allocations fully lazy

* Test message verification failure code/message

* Add grpctest verification test comments

* Simplify reallocate implementation

* Make initial_size a size_t

* Use ternary op for growth_policy

Calling std::move on a raw pointer has no advantage to just copying its value. Moreover, it is confusing, because it indicates that the argument is movable in some non-trivial way (e.g., is it actually meant to be a smart pointer?). More context in https://crbug.com/729393.

43611fcc0b refactor flatbuffers.h and util.h so FlexBuffers do not depend on flatbuffers.h (#4331)
FlexBuffers are actually completely unrelated to FlatBuffers and can be used separately.
However, since they utilize several utility functions from flatbuffer.h, they require this header file, which creates unreasonable dependency.
By moving those utility functions to separate base header, both libraries can use same code but still be independent

22743ca45a Fixed --keep-prefix functionality.
Changing to keep include prefixes had two side effects: the main
file being parsed wasn't filtered out anymore, and include directory
paths would be added to the path in the include statement.

Also moved the include_test*.fbs files to sub directories so we
can actually test the handling of -I etc.

tested: on Linux.

fb87c0d3c6 [C++] Improve Allocator handling (#4312)
* Improve Allocator handling

- Templatize Allocator on vector_downward, and make it own the allocator
instance so it can manage lifetimes.
- Templatize + rename FlatBufferBuilderT accordingly, and add a typedef
to FlatBufferBuilder so old code continues to work.
- Fix some issues with the release deleter
- More details in github issue #4311

* Fix constexpr for older MSVC

* Reimplement allocator improvements via inheritance

Instead of templates, use an abstract base class and some unique_ptrs to
implement the new and improved allocator.

* Fix misplaced newline

* Add missing override keyword

* Add macro for func delete to support older compilers

* Explicitly move BufferDeleter (maybe fixes VS 10?)

* Revert previous attempt at VS10 fix

* Try yet another workaround for MS 10

* Use FLATBUFFERS_NOEXCEPT macro

9aeeddf5ac C++/Go: Update gRPC related code to work with gRPC 1.3+ (#4305)
* Don't fail the build on unused parameters

gRPC headers have unused parameters so this breaks the test build.

* Pull in updated compiler files from gRPC

There have been some API breaks in gRPC lately. This commit
pulls in the most recent version of the files in this repo
that are just copied from gRPC.

* Modify the gRPC files so that they can work with Flatbuffers

The files taken from gRPC do not work out-of-the-box with Flatbuffers.
This commit modifies them so that they work. Hopefully this commit
will be able to serve as a guide or maybe even be cherry-picked on
top of new versions of those files as newer versions from gRPC are
pulled in.

* Adjust the rest of Flatbuffers to work with the new gRPC

* Change idl_gen_grpc.cpp to work with the new API
* Add missing #include in flatbuffers/grpc.h
* Run tests/generate_code.sh and check in the results
* Don't link with grpc++_unsecure and (secure) grpc. That's just weird

* Revert unrelated JS/TS test changes

* Simplify compiler/config.h

There is no need to import this file from gRPC. In fact, it probably
makes sense to not do so, since it seems to be intended to have
project specific configuration in it.

* Don't emit C++ types in the Go gRPC code generator

* Don't emit C++ #includes in generated gRPC code

Before this PR, there was a Go-specific additional_includes method
in schema_interface.h, which is shared with the gRPC repo. The
additional parameter to FlatBufFile in idl_gen_grpc.cpp makes that
unnecessary, which means we need less Flatbuffer-specific changes
in gRPC.

8b92122f33 Made the verifier catch zero-offsets.
Zero offsets are non-sensical in FlatBuffers (since offsets are
relative to themselves) but were allowed by the verifier. This could
cause buffers made up of all zeroes to be interpreted as correct
buffers with an empty root object.

Generally, not allowing such offsets will make the verifier more
likely to catch problems earlier.

Replaced size_t with uoffset_t for Verifier::max_tables_, max_depth_, depth_, and num_tables_ to ensure 32-bit values are used (and not 16-bit) - gave rise to a warning.

3f936c5655 More native code gen functionality.
Allow tables to be mapped to native types directly.  For example, a table
representing a vector3 (eg. table Vec3 { x:float; y:float; z:float; }) can
be mapped to a "mathfu::vec3" native type in NativeTables.  This requires
users to provide Pack and UnPack functions that convert between the
Table and native types.  This is done by adding the "native_type" attribute
to the table definition.

To support user-defined flatbuffers::Pack and flatbuffers::UnPack functions,
support a "native_include" markup that will generate a corresponding

Also add an UnPackTo function which allows users to pass in a pointer to
a NativeTable object into which to UnPack the Table.  The existing UnPack
function is now simply:

  NativeTable* UnPack() {
    NativeTable* obj = new NativeTable();
    Table::UnPackTo(obj);
    return obj;
  }

Finally, allow native types to be given a default value as well which are
set in the NativeTable constructor.  This is done by providing a
"native_default" attribute to the member of a table.

7b94eab2b1 Add CodeWriter utility class.
Helps simplify code generation code.  Instead of this:
  code += "inline const " + cpp_qualified_name + " *Get";
  code += name;
  code += "(const void *buf) {\n  return flatbuffers::GetRoot<";
  code += cpp_qualified_name + ">(buf);\n}\n\n";

You do this:
  code.SetValue("NAME", struct_def.name);
  code.SetValue("CPP_NAME", cpp_qualified_name);
  code += "inline const {{CPP_NAME}} *Get{{NAME}}(const void *buf) {";
  code += "  return flatbuffers::GetRoot<{{CPP_NAME}}>(buf);";
  code += "}";
  code += "";

Updated the CPP code generator to use the CodeWriter class.  Most of the
changes in the generated code are white-space changes, esp. around new
lines (since the code generator class automatically appends new lines
when appending a string).  Actual code changes include:

* Renamed "rehasher" to "_rehasher" for consistency with other args in
  Pack function.

* Renamed "union_obj" to "obj: in UnPack function.

* Always do "(void)_o;" to prevent unused variable warning in Create
  function (instead of only doing it if there are no fields) in order
  to avoid two-passes.

* Renamed padding variables from __paddingX to paddingX__.
  "Each name that contains a double underscore (_ _) [...] is reserved
   to the implementation for any use."  C++ standards 17.4.3.1.2.

* Add braces around switch cases.

* Calculate index as a separate statement in EnumName function, eg.
    const size_t index = ...;
    return EnumNamesX()[index];
  vs.
    return EnumNamesX()[...];

* Stored end table offset in variable in Finish() functions, eg.
    const auto end = fbb_.EndTable(start_, ...);
    auto o = flatbuffers::Offset<T>(end);
  vs.
    auto o = flatbuffers::Offset<T>(fbb_.EndTable(start, ...));

* Separate reinterpret_cast calls from function calls in Union
  functions, eg.
    auto ptr = reinterpret_cast<const T *>(obj);
    return ptr->UnPack(resolver);
  vs.
    return reinterpret_cast<const T *>(obj)->UnPack(resolver);

* Removed unecessary (void)(padding__X) no-ops from constructors, eg.
    Test(int16_t a, int8_t b) : ... {
      (void)__padding0;  // <-- Removed this line.
    }

In the idl_gen_cpp.cpp file itself, I refactored some code generation into
new functions: GenParam, GenNativeTable, GenVerifyCall, GenBuilders,
GenUnpackFieldStatement, and GenCreateParam.

f8a964d2b0 Fix call to Verifier::VerifyBuffer from BufferRef (#4124)
3a1f776132 added a required identifier parameter
to Verifier::VerifyBuffer but did not update the templated call site in
BufferRef. This causes errors like the following when trying to instantiate the
call site by calling BufferRef::Verify():

    include/flatbuffers/flatbuffers.h: In instantiation of ‘bool flatbuffers::BufferRef<T>::Verify() [with T = MyType]’:
    MyApp.cpp:16:3:   required from here
    include/flatbuffers/flatbuffers.h:1421:37: error: no matching function for call to ‘flatbuffers::Verifier::VerifyBuffer()’
         return verifier.VerifyBuffer<T>();
                                         ^
    include/flatbuffers/flatbuffers.h:1421:37: note: candidate is:
    include/flatbuffers/flatbuffers.h:1352:29: note: template<class T> bool flatbuffers::Verifier::VerifyBuffer(const char*)
       template<typename T> bool VerifyBuffer(const char *identifier) {
                                 ^
    include/flatbuffers/flatbuffers.h:1352:29: note:   template argument deduction/substitution failed:
    include/flatbuffers/flatbuffers.h:1421:37: note:   candidate expects 1 argument, 0 provided
         return verifier.VerifyBuffer<T>();
                                         ^

This commit fixes the BufferRef call site by adding a nullptr argument.

c66683f27f Add ::Set function to Unions to make memory ownership clear.
Unions own the NativeTable* value member because they need to destroy them
when the Union goes out of scope.  Currently, the data is destroyed by calling
delete, which means that the member needs to be allocated with new.  However,
making the allocation the responsibility of the client and the destruction
the responsibility of the Union can lead to potential errors.  Adding a
Set function will ensure that the memory is allocated correctly so that it
can be deleted later.

* Changes for verifying a buffer dynamically using reflection.

Fixing build issues on linux and applied code reformatting.

Fixing the file order in cmake file that was messing up the macro based code inclusion.

Added tests for reflection based verification.

* Incorporated the code review changes that were requested:

1. Changed the Verify function signature.
2. Changed the variable names to use snake_case.
3. Added better comments.
4. Refactored duplicate code.
5. Changed the verifier class so that it has the same size when compiled with or without FLATBUFFERS_TRACK_VERIFIER_BUFFER_SIZE macro.

* Setting FLATBUFFERS_TRACK_VERIFIER_BUFFER_SIZE and FLATBUFFERS_DEBUG_VERIFICATION_FAILURE through cmake for flattests so that it gets propagted to all translation units of flattests.

* Making the Verifier struct fields the same in all cases. Also reverting the target_compile_definitions change in cmake file because build machine on travis does not have cmake version 3.0 or higher which was the version when target_compile_definitions was added in cmake.

* Defining macros through cmake in a portable way using functions that are available in cmake 2.8.

bc2ec7119b Adds typedefs and functions to help write generic code.
The following changes have been made to the C++ codegen to enable writing generic code
that uses the Table and NativeTable types.

- Adds TableType and NativeTableType typedefs to NativeTable and Table structs.
- Adds GetFullyQualifiedName() to NativeTables if --gen-name-strings is set.
- Adds a static Pack function to Tables that simply calls the global CreateX functions.

See cr/140391505 as an example of improved usage.

This results in NativeTable code generation that sets the struct "inline" rather than
storing it in a pointer.

985de211af Fix Windows warnings.
Cmake issued a warning when the variable is in quotation marks
in an if statement.

Visual Studio upgrades constants to int and issues a truncation
warning, so inserted a cast.

5e7bfd0461 Isolate the complied Java classes into a target folder + log java version.
It is a common practice to put all the compiled classes into a
dedicated folder in order to:
 - avoid to mix the code and the complied classes
 - to allow a simple way to remove the complied classes

Add log of java version in order to make it explicit to the end user.

The new line in the set(CMAKE_CXX_FLAGS...) line was getting insert
verbatim into the Makefile. Makefiles don't like new lines in their
assignment operators.

The newline escape fix works for CMake 3.0 and above, but since
we support 2.x, we need to use the legacy solution, which is to
split into two separate statements.

Tested: cmake -G"Unix Makefiles" works now on Mac.

7c7c571bbe This is a minimal amount of #ifdef's to make stlport work.
Minimal, in the sense that this will only allow flatbuffers.h +
generated code to work. Everything else (tests, parsing, reflection
etc.) may still not compile with stlport.

Functionality has been reduced, some utility functions are not
available.

Tested: on Linux (no stlport), Android (stlport).

7a955a09f4 Move maven pom.xml from the java folder to the root folder.
This avoid to put the pom.xml file into the source directory. Normally the pom file is in a parent (/parent) folder and it is not mixed with the java source code.
An other thing is: this will make import of the project more easy from a IDE.

The side effect is that the target folder where maven build artifacts will move from the <flatbuffers>/java/target to <flatbuffers>/target therefore the gitignore file has been updated in consequences.

9875b0e0f8 Create a maven like project structure for java development. Make it OSGi compliant. Generate the flatbuffers code for testing (example).
Java developer are mostly comfortable with maven project structure. One one the main concept behind maven is convention. If you follow the maven project convention then your development team will get more effective as they now this project structure and can easily find the production code versus the test code.
 In this pull request I have structured the java project around 2 main parts:
  * the `flatbuffers` project. This project is the api / lib project and contains the test code structure + an example of code generation for testing. This avoid to commit generated code. Pre-configure JUnit for test driven development and make this project OSGi compliant.
  * the `jmh` project. This project aims to provide a placeholder for micro-benchmarking. JMH is a 'de facto' standard for micro benchmarking you can find more details here: http://openjdk.java.net/projects/code-tools/jmh/

For now I didn't move the JavaTest class but it could be a next step with a migration to the JUnit framework.
The only impacts are the move of the class and the project structure => no code change.

023fec627e Added helpers to access objects while creating the flatbuffer.
GetObject and GetMutableObject are similar to GetRoot and GetMutableRoot,
and can be useful when wanting to access data that has just been created.
Unfortunately there is a danger in using these methods, as it is possible
that the buffer reallocates which will invalidate the pointers.

6908826f95 Fix for #3849
This avoids the following allocations over repeated use:

- A ``CharsetEncoder``
- A byte array to contain the contents of the string
- A wrapper, via ``ByteBuffer#wrap``, for the previously mentioned byte
  array

This also removes a copy of the temporary byte array.  This extra copy
is needed because ``String#getBytes`` returns a byte array and its
length must match the exact size of the contents.

This implementation requires that the builder retain a ``ByteBuffer``
and ``CharEncoder``.  This is considered slower only for users that
will only allocate a single string in their buffers or none at all.

The improvement is especially potent if the builder is constantly reused
by its caller.  This also eliminates the penalty for users that do not
use strings at all since the cost of allocating these fields is
now amortized.

The only allocation left in this code is a ``CharBuffer`` wrapper.  It's
possible to eliminate this allocation using an additional copy but need
further profiling to see which is the bigger problem.

286587d151 Fix for #3853
Removes the following allocations:
- ``CharsetDecoder`` is reused between calls
- ``CharBuffer#wrap`` removed in favor of heap
  based char buffer that is reused
- Temporary ``char[]``, an intermediate copy inside ``StringCoding``
- Another ``char[]``, this is needed because ``StringCoding`` uses
  a ``CharBuffer`` internally but returns a ``char[]``.  Extra
  characters need to be trimmed so this means yet another allocation
- Yet another ``char[]`` directly from ``__string`` for non-heap
  based buffers

Removes the following copies
- No copy is performed to trim the allocation since a ``CharBuffer``
  is used directly
- For non-heap based byte buffers, removes the copy that was
  previously done in the __string function

This does need to get the TLS entry which implies at least some
contention on the thread object table and a fence.

2016-04-13 16:14:11 -07:00

039ab48b7a Stop CreateUninitializedVector returning a pointer to invalid memory.
CreateUninitializedVector was performing the following actions:
    1. call StartVector.
    2. call make_space, and set buf to point to the reserved space.
    3. call EndVector.

The problem is that a call to EndVector can ultimately call make_space, which
if the buffer is full, will cause a reallocation, invalidating the value stored
in buf.  So setting buf needs to be delayed until after EndVector.

The following code, when run under valgrind shows a write to free'd memory before
the change, but no such error after:

int main()
{
    flatbuffers::FlatBufferBuilder fbb(128);
    char *buf = nullptr;
    fbb.CreateUninitializedVector(128, &buf);
    *buf = 0;
}

28a3c939e7 Implement __vector_as_bytes and methods to get [ubyte] efficiently
Currently in order to get a value type of [ubyte] in PHP, iteration is
necessary which is not efficient. Helper __vector_as_bytes has been
implemented in order to return the byte arrays in PHP efficiently.

Appropriate methods also been added to use aforementioned method to return
the byte array. (e.g. get*Bytes()).

The reason the methods are named get*Bytes() and not for instance
get*ByteArray() is the fact that PHP doesn't support byte arrays and the
binary safe string implementation in PHP is used to simulate byte arrays
and since there is chance for PHP users to confuse this with PHP arrays
the name get*Bytes() has been chosen.

In the future __vector_as_bytebuffer() method can also be implemented to
return PHP implementation of ByteBuffer.

1e7310e6cd Fix CreateString with already-encoded string or bytearray in Python 2.7.
There was no way to pass an already-encoded string to 
`builder.CreateString` in Python 2.7:

- Passing a `bytearray` raised a TypeError because `bytearray` was not
  recognized as an instance of `compat.binary_type`.
- Passing a utf-8 encoded `str` would cause the string to be
  double-encoded, because `compat.string_types = (basestring,)` and
  `basestring` is the base class of `str` and `unicode`, so the logic
  would never reach the `elif isinstance(s, compat.binary_type)` case.
- Converting a utf-8 encoded bytearray to `bytes` like
  `builder.CreateString(bytes(encoded_string))` does not work because
  in Python 2.7, bytes is just an alias for `str` so it behaves as
  above.

This change allows either `bytes` or `bytearray` as an already-encoded
string to be passed to `CreateString` in versions of Python that support
`bytearray`, and falls back to `str` in older versions.

In Python 2, it restricts unencoded string types to `unicode`, so `str`
can be used as an encoded, binary representaiton.

ac49eda053 Multiple schemas parsed by flatc are now parsed independently.
It used to be such that later schemas could depend on earlier
schemas. This was a convenience from days before include files
were implemented. Nowadays they cause subtle bugs rather than being
useful, so this functionality has been removed.

You now need to explicitly include files you depend upon.

Please make sure you include the names of the affected language(s) in your PR title.
This helps us get the correct maintainers to look at your issue.
If you make changes to any of the code generators, be sure to run
`cd tests && sh generate_code.sh` (or equivalent .bat) and include the generated
code changes in the PR. This allows us to better see the effect of the PR.
If your PR includes C++ code, please adhere to the Google C++ Style Guide,
and don't forget we try to support older compilers (e.g. VS2010, GCC 4.6.3),

Use in C {#flatbuffers_guide_use_c}
==========
The C language binding exists in a separate project named [FlatCC](https://github.com/dvidelabs/flatcc).
The `flatcc` C schema compiler can generate code offline as well as
online via a C library. It can also generate buffer verifiers and fast
JSON parsers, printers.
Great care has been taken to ensure compatibily with the main `flatc`
project.
## General Documention
- [Tutorial](@ref flatbuffers_guide_tutorial) - select C as language
when scrolling down
- [FlatCC Guide](https://github.com/dvidelabs/flatcc#flatcc-flatbuffers-in-c-for-c)
- [The C Builder Interface](https://github.com/dvidelabs/flatcc/blob/master/doc/builder.md#the-builder-interface)
- [The Monster Sample in C](https://github.com/dvidelabs/flatcc/blob/master/samples/monster/monster.c)
- [GitHub](https://github.com/dvidelabs/flatcc)
## Supported Platforms
- Ubuntu (clang / gcc, ninja / gnu make)
- OS-X (clang / gcc, ninja / gnu make)
- Windows MSVC 2010, 2013, 2015
CI builds recent versions of gcc, clang and MSVC on OS-X, Ubuntu, and
Windows, and occasionally older compiler versions. See main project [Status](https://github.com/dvidelabs/flatcc#status).
Other platforms may well work, including Centos, but are not tested
regularly.
The monster sample project was specifically written for C99 in order to
follow the C++ version and for that reason it will not work with MSVC
2010.
## Modular Object Creation
In the tutorial we used the call `Monster_create_as_root` to create the
root buffer object since this is easier in simple use cases. Sometimes
we need more modularity so we can reuse a function to create nested
tables and root tables the same way. For this we need the
`flatcc_builder_buffer_create_call`. It is best to keep `flatcc_builder`
calls isolated at the top driver level, so we get:
<div class="language-c">
~~~{.c}
ns(Monster_ref_t) create_orc(flatcc_builder_t *B)
{
// ... same as in the tutorial.
return s(Monster_create(B, ...));
}
void create_monster_buffer()
{
uint8_t *buf;
size_t size;
flatcc_builder_t builder, *B;
// Initialize the builder object.
B = &builder;
flatcc_builder_init(B);
// Only use `buffer_create` without `create/start/end_as_root`.
flatcc_builder_buffer_create(create_orc(B));
// Allocate and copy buffer to user memory.
buf = flatcc_builder_finalize_buffer(B, &size);
// ... write the buffer to disk or network, or something.
free(buf);
flatcc_builder_clear(B);
}
~~~
</div>
The same principle applies with `start/end` vs `start/end_as_root` in
the top-down approach.
## Top Down Example
The tutorial uses a bottom up approach. In C it is also possible to use
a top-down approach by starting and ending objects nested within each
other. In the tutorial there is no deep nesting, so the difference is
limited, but it shows the idea:
<div class="language-c">
<br>
~~~{.c}
uint8_t treasure[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
size_t treasure_count = c_vec_len(treasure);
ns(Weapon_ref_t) axe;
// NOTE: if we use end_as_root, we MUST also start as root.
ns(Monster_start_as_root(B));
ns(Monster_pos_create(B, 1.0f, 2.0f, 3.0f));
ns(Monster_hp_add(B, 300));
ns(Monster_mana_add(B, 150));
// We use create_str instead of add because we have no existing string reference.
ns(Monster_name_create_str(B, "Orc"));
// Again we use create because we no existing vector object, only a C-array.
ns(Monster_inventory_create(B, treasure, treasure_count));
ns(Monster_color_add(B, ns(Color_Red)));
if (1) {
ns(Monster_weapons_start(B));
ns(Monster_weapons_push_create(B, flatbuffers_string_create_str(B, "Sword"), 3));
// We reuse the axe object later. Note that we dereference a pointer
// because push always returns a short-term pointer to the stored element.
// We could also have created the axe object first and simply pushed it.
axe = *ns(Monster_weapons_push_create(B, flatbuffers_string_create_str(B, "Axe"), 5));
ns(Monster_weapons_end(B));
} else {
// We can have more control with the table elements added to a vector:
//
ns(Monster_weapons_start(B));
ns(Monster_weapons_push_start(B));
ns(Weapon_name_create_str(B, "Sword"));
ns(Weapon_damage_add(B, 3));
ns(Monster_weapons_push_end(B));
ns(Monster_weapons_push_start(B));
ns(Monster_weapons_push_start(B));
ns(Weapon_name_create_str(B, "Axe"));
ns(Weapon_damage_add(B, 5));
axe = *ns(Monster_weapons_push_end(B));
ns(Monster_weapons_end(B));
}
// Unions can get their type by using a type-specific add/create/start method.
ns(Monster_equipped_Weapon_add(B, axe));
ns(Monster_end_as_root(B));

## Basic Reflection
The C-API does support reading binary schema (.bfbs)
files via code generated from the `reflection.fbs` schema, and an
[example usage](https://github.com/dvidelabs/flatcc/tree/master/samples/reflection)
shows how to use this. The reflection schema files are pre-generated
in the [runtime distribution](https://github.com/dvidelabs/flatcc/tree/master/include/flatcc/reflection).
## Mutations and Reflection
The C-API does not support mutating reflection like C++ does, nor does
the reader interface support mutating scalars (and it is generally
unsafe to do so even after verification).
The generated reader interface supports sorting vectors in-place after
casting them to a mutating type because it is not practical to do so
while building a buffer. This is covered in the builder documentation.
The reflection example makes use of this feature to look up objects by
name.
It is possible to build new buffers using complex objects from existing
buffers as source. This can be very efficient due to direct copy
semantics without endian conversion or temporary stack allocation.
Scalars, structs and strings can be used as source, as well vectors of
these.
It is currently not possible to use an existing table or vector of table
as source, but it would be possible to add support for this at some
point.
## Namespaces
The `FLATBUFFERS_WRAP_NAMESPACE` approach used in the tutorial is convenient
when each function has a very long namespace prefix. But it isn't always
the best approach. If the namespace is absent, or simple and
informative, we might as well use the prefix directly. The
[reflection example](https://github.com/dvidelabs/flatcc/blob/master/samples/reflection/bfbs2json.c)
mentioned above uses this approach.
## Checking for Present Members
Not all languages support testing if a field is present, but in C we can
elaborate the reader section of the tutorial with tests for this. Recall
that `mana` was set to the default value `150` and therefore shouldn't
be present.
<div class="language-c">
~~~{.c}
int hp_present = ns(Monster_hp_is_present(monster)); // 1
int mana_present = ns(Monster_mana_is_present(monster)); // 0
~~~
</div>
## Alternative ways to add a Union
In the tutorial we used a single call to add a union. Here we show
different ways to accomplish the same thing. The last form is rarely
used, but is the low-level way to do it. It can be used to group small
values together in the table by adding type and data at different
points in time.
<div class="language-c">
~~~{.c}
ns(Equipment_union_ref_t) equipped = ns(Equipment_as_Weapon(axe));
ns(Monster_equipped_add(B, equipped));
// or alternatively
ns(Monster_equipped_Weapon_add(B, axe);
// or alternatively
ns(Monster_equipped_add_type(B, ns(Equipment_Weapon));
ns(Monster_equipped_add_member(B, axe));
~~~
</div>
## Why not integrate with the `flatc` tool?
[It was considered how the C code generator could be integrated into the
`flatc` tool](https://github.com/dvidelabs/flatcc/issues/1), but it
would either require that the standalone C implementation of the schema
compiler was dropped, or it would lead to excessive code duplication, or
a complicated intermediate representation would have to be invented.
Neither of these alternatives are very attractive, and it isn't a big
deal to use the `flatcc` tool instead of `flatc` given that the
FlatBuffers C runtime library needs to be made available regardless.

## Object based API. {#flatbuffers_cpp_object_based_api}
FlatBuffers is all about memory efficiency, which is why its base API is written
around using as little as possible of it. This does make the API clumsier
(requiring pre-order construction of all data, and making mutation harder).
For times when efficiency is less important a more convenient object based API
can be used (through `--gen-object-api`) that is able to unpack & pack a
FlatBuffer into objects and standard STL containers, allowing for convenient
construction, access and mutation.
To use:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
// Autogenerated class from table Monster.
MonsterT monsterobj;
// Deserialize from buffer into object.
UnPackTo(&monsterobj, flatbuffer);
// Update object directly like a C++ class instance.
cout << monsterobj->name; // This is now a std::string!
monsterobj->name = "Bob"; // Change the name.
// Serialize into new flatbuffer.
FlatBufferBuilder fbb;
Pack(fbb, &monsterobj);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The following attributes are specific to the object-based API code generation:
- `native_inline` (on a field): Because FlatBuffer tables and structs are
optionally present in a given buffer, they are best represented as pointers
(specifically std::unique_ptrs) in the native class since they can be null.
This attribute changes the member declaration to use the type directly
rather than wrapped in a unique_ptr.
- `native_default`: "value" (on a field): For members that are declared
"native_inline", the value specified with this attribute will be included
verbatim in the class constructor initializer list for this member.
- `native_custom_alloc`:"custom_allocator" (on a table or struct): When using the
object-based API all generated NativeTables that are allocated when unpacking
your flatbuffer will use "custom allocator". The allocator is also used by
any std::vector that appears in a table defined with `native_custom_alloc`.
This can be used to provide allocation from a pool for example, for faster
unpacking when using the object-based API.
Minimal Example:
schema:
table mytable(native_custom_alloc:"custom_allocator") {
...
}
with custom_allocator defined before flatbuffers.h is included, as:
template <typename T> struct custom_allocator : public std::allocator<T> {
typedef T *pointer;
template <class U>
struct rebind {
typedef custom_allocator<U> other;
};
pointer allocate(const std::size_t n) {
return std::allocator<T>::allocate(n);
}
void deallocate(T* ptr, std::size_t n) {
return std::allocator<T>::deallocate(ptr,n);
}
custom_allocator() throw() {}
template <class U>
custom_allocator(const custom_allocator<U>&) throw() {}
};
- `native_type`' "type" (on a struct): In some cases, a more optimal C++ data
type exists for a given struct. For example, the following schema:
struct Vec2 {
x: float;
y: float;
}
generates the following Object-Based API class:
struct Vec2T : flatbuffers::NativeTable {
float x;
float y;
};
However, it can be useful to instead use a user-defined C++ type since it
can provide more functionality, eg.
struct vector2 {
float x = 0, y = 0;
vector2 operator+(vector2 rhs) const { ... }
vector2 operator-(vector2 rhs) const { ... }
float length() const { ... }
// etc.
};
The `native_type` attribute will replace the usage of the generated class
with the given type. So, continuing with the example, the generated
code would use |vector2| in place of |Vec2T| for all generated code.
However, becuase the native_type is unknown to flatbuffers, the user must
provide the following functions to aide in the serialization process:
namespace flatbuffers {
FlatbufferStruct Pack(const native_type& obj);
native_type UnPack(const FlatbufferStruct& obj);
}
Finally, the following top-level attribute
- native_include: "path" (at file level): Because the `native_type` attribute
can be used to introduce types that are unknown to flatbuffers, it may be
necessary to include "external" header files in the generated code. This
attribute can be used to directly add an #include directive to the top of
the generated code that includes the specified path directly.
# External references.
An additional feature of the object API is the ability to allow you to load
multiple independent FlatBuffers, and have them refer to eachothers objects
using hashes which are then represented as typed pointers in the object API.
To make this work have a field in the objects you want to referred to which is
using the string hashing feature (see `hash` attribute in the
[schema](@ref flatbuffers_guide_writing_schema) documentation). Then you have
a similar hash in the field referring to it, along with a `cpp_type`
attribute specifying the C++ type this will refer to (this can be any C++
type, and will get a `*` added).
Then, in JSON or however you create these buffers, make sure they use the
same string (or hash).
When you call `UnPack` (or `Create`), you'll need a function that maps from
hash to the object (see `resolver_function_t` for details).
# Using different pointer types.
By default the object tree is built out of `std::unique_ptr`, but you can
influence this either globally (using the `--cpp-ptr-type` argument to
`flatc`) or per field (using the `cpp_ptr_type` attribute) to by any smart
pointer type (`my_ptr<T>`), or by specifying `naked` as the type to get `T *`
pointers. Unlike the smart pointers, naked pointers do not manage memory for
you, so you'll have to manage their lifecycles manually.
# Using different string type.
By default the object tree is built out of `std::string`, but you can
influence this either globally (using the `--cpp-str-type` argument to

## Mini Reflection
A more limited form of reflection is available for direct inclusion in
generated code, which doesn't any (binary) schema access at all. It was designed
to keep the overhead of reflection as low as possible (on the order of 2-6
bytes per field added to your executable), but doesn't contain all the
information the (binary) schema contains.
You add this information to your generated code by specifying `--reflect-types`
(or instead `--reflect-names` if you also want field / enum names).
You can now use this information, for example to print a FlatBuffer to text:
auto s = flatbuffers::FlatBufferToString(flatbuf, MonsterTypeTable());
`MonsterTypeTable()` is declared in the generated code for each type. The
string produced is very similar to the JSON produced by the `Parser` based
text generator.
You'll need `flatbuffers/minireflect.h` for this functionality. In there is also
a convenient visitor/iterator so you can write your own output / functionality

FlexBuffers {#flexbuffers}
==========
FlatBuffers was designed around schemas, because when you want maximum
performance and data consistency, strong typing is helpful.
There are however times when you want to store data that doesn't fit a
schema, because you can't know ahead of time what all needs to be stored.
For this, FlatBuffers has a dedicated format, called FlexBuffers.
This is a binary format that can be used in conjunction
with FlatBuffers (by storing a part of a buffer in FlexBuffers
format), or also as its own independent serialization format.
While it loses the strong typing, you retain the most unique advantage
FlatBuffers has over other serialization formats (schema-based or not):
FlexBuffers can also be accessed without parsing / copying / object allocation.
This is a huge win in efficiency / memory friendly-ness, and allows unique
use cases such as mmap-ing large amounts of free-form data.
FlexBuffers' design and implementation allows for a very compact encoding,
combining automatic pooling of strings with automatic sizing of containers to
their smallest possible representation (8/16/32/64 bits). Many values and
offsets can be encoded in just 8 bits. While a schema-less representation is
usually more bulky because of the need to be self-descriptive, FlexBuffers
generates smaller binaries for many cases than regular FlatBuffers.
FlexBuffers is still slower than regular FlatBuffers though, so we recommend to
only use it if you need it.
# Usage
This is for C++, other languages may follow.
Include the header `flexbuffers.h`, which in turn depends on `flatbuffers.h`
and `util.h`.
To create a buffer:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
flexbuffers::Builder fbb;
fbb.Int(13);
fbb.Finish();
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You create any value, followed by `Finish`. Unlike FlatBuffers which requires
the root value to be a table, here any value can be the root, including a lonely
int value.
You can now access the `std::vector<uint8_t>` that contains the encoded value
as `fbb.GetBuffer()`. Write it, send it, or store it in a parent FlatBuffer. In
this case, the buffer is just 3 bytes in size.
To read this value back, you could just say:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
auto root = flexbuffers::GetRoot(my_buffer);
int64_t i = root.AsInt64();
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
FlexBuffers stores ints only as big as needed, so it doesn't differentiate
between different sizes of ints. You can ask for the 64 bit version,
regardless of what you put in. In fact, since you demand to read the root
as an int, if you supply a buffer that actually contains a float, or a
string with numbers in it, it will convert it for you on the fly as well,
or return 0 if it can't. If instead you actually want to know what is inside
the buffer before you access it, you can call `root.GetType()` or `root.IsInt()`
etc.
Here's a slightly more complex value you could write instead of `fbb.Int` above:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
fbb.Map([&]() {
fbb.Vector("vec", [&]() {
fbb.Int(-100);
fbb.String("Fred");
fbb.IndirectFloat(4.0f);
});
fbb.UInt("foo", 100);
});
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This stores the equivalent of the JSON value
`{ vec: [ -100, "Fred", 4.0 ], foo: 100 }`. The root is a dictionary that has
just two key-value pairs, with keys `vec` and `foo`. Unlike FlatBuffers, it
actually has to store these keys in the buffer (which it does only once if
you store multiple such objects, by pooling key values), but also unlike
FlatBuffers it has no restriction on the keys (fields) that you use.
The map constructor uses a C++11 Lambda to group its children, but you can
also use more conventional start/end calls if you prefer.
The first value in the map is a vector. You'll notice that unlike FlatBuffers,
you can use mixed types. There is also a `TypedVector` variant that only
allows a single type, and uses a bit less memory.
`IndirectFloat` is an interesting feature that allows you to store values
by offset rather than inline. Though that doesn't make any visible change
to the user, the consequence is that large values (especially doubles or
64 bit ints) that occur more than once can be shared. Another use case is
inside of vectors, where the largest element makes up the size of all elements
(e.g. a single double forces all elements to 64bit), so storing a lot of small
integers together with a double is more efficient if the double is indirect.
Accessing it:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
auto map = flexbuffers::GetRoot(my_buffer).AsMap();
map.size(); // 2
auto vec = map["vec"].AsVector();
vec.size(); // 3
vec[0].AsInt64(); // -100;
vec[1].AsString().c_str(); // "Fred";
vec[1].AsInt64(); // 0 (Number parsing failed).
vec[2].AsDouble(); // 4.0
vec[2].AsString().IsTheEmptyString(); // true (Wrong Type).
vec[2].AsString().c_str(); // "" (This still works though).
vec[2].ToString().c_str(); // "4" (Or have it converted).
map["foo"].AsUInt8(); // 100
map["unknown"].IsNull(); // true
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Binary encoding
A description of how FlexBuffers are encoded is in the
[internals](@ref flatbuffers_internals) document.
# Nesting inside a FlatBuffer
You can mark a field as containing a FlexBuffer, e.g.
a:[ubyte] (flexbuffer);
A special accessor will be generated that allows you to access the root value
directly, e.g. `a_flexbuffer_root().AsInt64()`.
# Efficiency tips
* Vectors generally are a lot more efficient than maps, so prefer them over maps
when possible for small objects. Instead of a map with keys `x`, `y` and `z`,
use a vector. Better yet, use a typed vector. Or even better, use a fixed
size typed vector.
* Maps are backwards compatible with vectors, and can be iterated as such.
You can iterate either just the values (`map.Values()`), or in parallel with
the keys vector (`map.Keys()`). If you intend
to access most or all elements, this is faster than looking up each element
by key, since that involves a binary search of the key vector.
* When possible, don't mix values that require a big bit width (such as double)
in a large vector of smaller values, since all elements will take on this
width. Use `IndirectDouble` when this is a possibility. Note that
integers automatically use the smallest width possible, i.e. if you ask
to serialize an int64_t whose value is actually small, you will use less
bits. Doubles are represented as floats whenever possible losslessly, but
this is only possible for few values.
Since nested vectors/maps are stored over offsets, they typically don't
affect the vector width.
* To store large arrays of byte data, use a blob. If you'd use a typed
vector, the bit width of the size field may make it use more space than
expected, and may not be compatible with `memcpy`.
Similarly, large arrays of (u)int16_t may be better off stored as a
binary blob if their size could exceed 64k elements.
Construction and use are otherwise similar to strings.

### Additional reading.
The author of the C language implementation has made a similar
[document](https://github.com/dvidelabs/flatcc/blob/master/doc/binary-format.md#flatbuffers-binary-format)
that may further help clarify the format.
# FlexBuffers
The [schema-less](@ref flexbuffers) version of FlatBuffers have their
own encoding, detailed here.
It shares many properties mentioned above, in that all data is accessed
over offsets, all scalars are aligned to their own size, and
all data is always stored in little endian format.
One difference is that FlexBuffers are built front to back, so children are
stored before parents, and the root of the data starts at the last byte.
Another difference is that scalar data is stored with a variable number of bits
(8/16/32/64). The current width is always determined by the *parent*, i.e. if
the scalar sits in a vector, the vector determines the bit width for all
elements at once. Selecting the minimum bit width for a particular vector is
something the encoder does automatically and thus is typically of no concern
to the user, though being aware of this feature (and not sticking a double in
the same vector as a bunch of byte sized elements) is helpful for efficiency.
Unlike FlatBuffers there is only one kind of offset, and that is an unsigned
integer indicating the number of bytes in a negative direction from the address
of itself (where the offset is stored).
### Vectors
The representation of the vector is at the core of how FlexBuffers works (since
maps are really just a combination of 2 vectors), so it is worth starting there.
As mentioned, a vector is governed by a single bit width (supplied by its
parent). This includes the size field. For example, a vector that stores the
integer values `1, 2, 3` is encoded as follows:
uint8_t 3, 1, 2, 3, 4, 4, 4
The first `3` is the size field, and is placed before the vector (an offset
from the parent to this vector points to the first element, not the size
field, so the size field is effectively at index -1).
Since this is an untyped vector `SL_VECTOR`, it is followed by 3 type
bytes (one per element of the vector), which are always following the vector,
and are always a uint8_t even if the vector is made up of bigger scalars.
### Types
A type byte is made up of 2 components (see flexbuffers.h for exact values):
* 2 lower bits representing the bit-width of the child (8, 16, 32, 64).
This is only used if the child is accessed over an offset, such as a child
vector. It is ignored for inline types.
* 6 bits representing the actual type (see flexbuffers.h).
Thus, in this example `4` means 8 bit child (value 0, unused, since the value is
in-line), type `SL_INT` (value 1).
### Typed Vectors
These are like the Vectors above, but omit the type bytes. The type is instead
determined by the vector type supplied by the parent. Typed vectors are only
available for a subset of types for which these savings can be significant,
namely inline signed/unsigned integers (`TYPE_VECTOR_INT` / `TYPE_VECTOR_UINT`),
floats (`TYPE_VECTOR_FLOAT`), and keys (`TYPE_VECTOR_KEY`, see below).
Additionally, for scalars, there are fixed length vectors of sizes 2 / 3 / 4
that don't store the size (`TYPE_VECTOR_INT2` etc.), for an additional savings
in space when storing common vector or color data.
### Scalars
FlexBuffers supports integers (`TYPE_INT` and `TYPE_UINT`) and floats
(`TYPE_FLOAT`), available in the bit-widths mentioned above. They can be stored
both inline and over an offset (`TYPE_INDIRECT_*`).
The offset version is useful to encode costly 64bit (or even 32bit) quantities
into vectors / maps of smaller sizes, and to share / repeat a value multiple
times.
### Booleans and Nulls
Booleans (`TYPE_BOOL`) and nulls (`TYPE_NULL`) are encoded as inlined unsigned integers.
### Blobs, Strings and Keys.
A blob (`TYPE_BLOB`) is encoded similar to a vector, with one difference: the
elements are always `uint8_t`. The parent bit width only determines the width of
the size field, allowing blobs to be large without the elements being large.
Strings (`TYPE_STRING`) are similar to blobs, except they have an additional 0
termination byte for convenience, and they MUST be UTF-8 encoded (since an
accessor in a language that does not support pointers to UTF-8 data may have to
convert them to a native string type).
A "Key" (`TYPE_KEY`) is similar to a string, but doesn't store the size
field. They're so named because they are used with maps, which don't care
for the size, and can thus be even more compact. Unlike strings, keys cannot
contain bytes of value 0 as part of their data (size can only be determined by
`strlen`), so while you can use them outside the context of maps if you so
desire, you're usually better off with strings.
### Maps
A map (`TYPE_MAP`) is like an (untyped) vector, but with 2 prefixes before the
size field:
| index | field |
| ----: | :----------------------------------------------------------- |
| -3 | An offset to the keys vector (may be shared between tables). |
| -2 | Byte width of the keys vector. |
| -1 | Size (from here on it is compatible with `TYPE_VECTOR`) |
| 0 | Elements. |
| Size | Types. |
Since a map is otherwise the same as a vector, it can be iterated like
a vector (which is probably faster than lookup by key).
The keys vector is a typed vector of keys. Both the keys and corresponding
values *have* to be stored in sorted order (as determined by `strcmp`), such
that lookups can be made using binary search.
The reason the key vector is a seperate structure from the value vector is
such that it can be shared between multiple value vectors, and also to
allow it to be treated as its own individual vector in code.
An example map { foo: 13, bar: 14 } would be encoded as:
0 : uint8_t 'b', 'a', 'r', 0
4 : uint8_t 'f', 'o', 'o', 0
8 : uint8_t 2 // key vector of size 2
// key vector offset points here
9 : uint8_t 9, 6 // offsets to bar_key and foo_key
11: uint8_t 2, 1 // offset to key vector, and its byte width
13: uint8_t 2 // value vector of size
// value vector offset points here
14: uint8_t 14, 13 // values
16: uint8_t 4, 4 // types
### The root
As mentioned, the root starts at the end of the buffer.
The last uint8_t is the width in bytes of the root (normally the parent
determines the width, but the root has no parent). The uint8_t before this is
the type of the root, and the bytes before that are the root value (of the
number of bytes specified by the last byte).
So for example, the integer value `13` as root would be:
uint8_t 13, 4, 1 // Value, type, root byte width.

## Storing dictionaries in a FlatBuffer
FlatBuffers doesn't support dictionaries natively, but there is support to
emulate their behavior with vectors and binary search, which means you
can have fast lookups directly from a FlatBuffer without having to unpack
your data into a `Dictionary` or similar.
To use it:
- Designate one of the fields in a table as the "key" field. You do this
by setting the `key` attribute on this field, e.g.
`name:string (key)`.
You may only have one key field, and it must be of string or scalar type.
- Write out tables of this type as usual, collect their offsets in an
array.
- Instead of calling standard generated method,
e.g.: `Monster.createTestarrayoftablesVector`,
call `CreateSortedVectorOfMonster` in C# or
`createSortedVectorOfTables` (from the `FlatBufferBuilder` object) in Java,
which will first sort all offsets such that the tables they refer to
are sorted by the key field, then serialize it.
- Now when you're accessing the FlatBuffer, you can use
the `ByKey` accessor to access elements of the vector, e.g.:
`monster.testarrayoftablesByKey("Frodo")` in Java or
`monster.TestarrayoftablesByKey("Frodo")` in C#,
which returns an object of the corresponding table type,
or `null` if not found.
`ByKey` performs a binary search, so should have a similar
speed to `Dictionary`, though may be faster because of better caching.
`ByKey` only works if the vector has been sorted, it will
likely not find elements if it hasn't been sorted.

## Support for Numpy arrays
The Flatbuffers python library also has support for accessing scalar
vectors as numpy arrays. This can be orders of magnitude faster than
iterating over the vector one element at a time, and is particularly
useful when unpacking large nested flatbuffers. The generated code for
a scalar vector will have a method `<vector name>AsNumpy()`. In the
case of the Monster example, you could access the inventory vector
like this:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.py}
inventory = monster.InventoryAsNumpy()

## Guidelines
### Efficiency
FlatBuffers is all about efficiency, but to realize that efficiency you
require an efficient schema. There are usually multiple choices on
how to represent data that have vastly different size characteristics.
It is very common nowadays to represent any kind of data as dictionaries
(as in e.g. JSON), because of its flexibility and extensibility. While
it is possible to emulate this in FlatBuffers (as a vector
of tables with key and value(s)), this is a bad match for a strongly
typed system like FlatBuffers, leading to relatively large binaries.
FlatBuffer tables are more flexible than classes/structs in most systems,
since having a large number of fields only few of which are actually
used is still efficient. You should thus try to organize your data
as much as possible such that you can use tables where you might be
tempted to use a dictionary.
Similarly, strings as values should only be used when they are
truely open-ended. If you can, always use an enum instead.
FlatBuffers doesn't have inheritance, so the way to represent a set
of related data structures is a union. Unions do have a cost however,
so an alternative to a union is to have a single table that has
all the fields of all the data structures you are trying to
represent, if they are relatively similar / share many fields.
Again, this is efficient because optional fields are cheap.
FlatBuffers supports the full range of integer sizes, so try to pick
the smallest size needed, rather than defaulting to int/long.
Remember that you can share data (refer to the same string/table
within a buffer), so factoring out repeating data into its own
data structure may be worth it.
### Style guide
Identifiers in a schema are meant to translate to many different programming
languages, so using the style of your "main" language is generally a bad idea.
For this reason, below is a suggested style guide to adhere to, to keep schemas
consistent for interoperation regardless of the target language.
Where possible, the code generators for specific languages will generate
identifiers that adhere to the language style, based on the schema identifiers.
- Table, struct, enum and rpc names (types): UpperCamelCase.
- Table and struct field names: snake_case. This is translated to lowerCamelCase
automatically for some languages, e.g. Java.
- Enum values: UpperCamelCase.
- namespaces: UpperCamelCase.
Formatting (this is less important, but still worth adhering to):
- Opening brace: on the same line as the start of the declaration.
- Spacing: Indent by 2 spaces. None around `:` for types, on both sides for `=`.
For an example, see the schema at the top of this file.

fields by id/offset.
<br>
### Testing whether a field is present in a table
Most serialization formats (e.g. JSON or Protocol Buffers) make it very
explicit in the format whether a field is present in an object or not,
allowing you to use this as "extra" information.
In FlatBuffers, this also holds for everything except scalar values.
FlatBuffers by default will not write fields that are equal to the default
value (for scalars), sometimes resulting in a significant space savings.
However, this also means testing whether a field is "present" is somewhat
meaningless, since it does not tell you if the field was actually written by
calling `add_field` style calls, unless you're only interested in this
information for non-default values.
Some `FlatBufferBuilder` implementations have an option called `force_defaults`
that circumvents this behavior, and writes fields even if they are equal to
the default. You can then use `IsFieldPresent` to query this.
Another option that works in all languages is to wrap a scalar field in a
struct. This way it will return null if it is not present. The cool thing
is that structs don't take up any more space than the scalar they represent.

Use in TypeScript {#flatbuffers_guide_use_typescript}
=================
## Before you get started
Before diving into the FlatBuffers usage in TypeScript, it should be noted that
the [Tutorial](@ref flatbuffers_guide_tutorial) page has a complete guide to
general FlatBuffers usage in all of the supported languages
(including TypeScript). This page is specifically designed to cover the nuances
of FlatBuffers usage in TypeScript.
You should also have read the [Building](@ref flatbuffers_guide_building)
documentation to build `flatc` and should be familiar with
[Using the schema compiler](@ref flatbuffers_guide_using_schema_compiler) and
[Writing a schema](@ref flatbuffers_guide_writing_schema).
## FlatBuffers TypeScript library code location
The code for the FlatBuffers TypeScript library can be found at
`flatbuffers/js` with typings available at @types/flatubffers.
## Testing the FlatBuffers TypeScript library
To run the tests, use the [TypeScriptTest.sh](https://github.com/google/
flatbuffers/blob/master/tests/TypeScriptTest.sh) shell script.
*Note: The TypeScript test file requires [Node.js](https://nodejs.org/en/).*
## Using the FlatBuffers TypeScript libary
*Note: See [Tutorial](@ref flatbuffers_guide_tutorial) for a more in-depth
example of how to use FlatBuffers in TypeScript.*
FlatBuffers supports both reading and writing FlatBuffers in TypeScript.
To use FlatBuffers in your own code, first generate TypeScript classes from your
schema with the `--ts` option to `flatc`. Then you can include both FlatBuffers
and the generated code to read or write a FlatBuffer.
For example, here is how you would read a FlatBuffer binary file in TypeScript:
First, include the library and generated code. Then read the file into an
`Uint8Array`. Make a `flatbuffers.ByteBuffer` out of the `Uint8Array`, and pass
the ByteBuffer to the `getRootAsMonster` function.
~~~{.ts}
// note: import flabuffers with your desired import method
import { MyGame } from './monster_generated';
let data = new Uint8Array(fs.readFileSync('monster.dat'));
let buf = new flatbuffers.ByteBuffer(data);
let monster = MyGame.Example.Monster.getRootAsMonster(buf);
~~~
Now you can access values like this:
~~~{.ts}
let hp = monster.hp();
let pos = monster.pos();
~~~
## Text parsing FlatBuffers in TypeScript
There currently is no support for parsing text (Schema's and JSON) directly
from TypeScript.

We will illustrate usage with the following schema:
@include grpc/samples/greeter/greeter.fbs
When we run `flatc`, we pass in the `--grpc` option and generage an additional
`greeter.grpc.fb.h` and `greeter.grpc.fb.cc`.
Example server code looks like this:
@include grpc/samples/greeter/server.cpp
Example client code looks like this:

GRPC implementation and test
============================
NOTE: files in `src/` are shared with the GRPC project, and maintained there
(any changes should be submitted to GRPC instead). These files are copied
from GRPC, and work with both the Protobuf and FlatBuffers code generator.
`tests/` contains a GRPC specific test, you need to have built and installed
the GRPC libraries for this to compile. This test will build using the
`FLATBUFFERS_BUILD_GRPCTEST` option to the main FlatBuffers CMake project.
