For example:
include/flatbuffers/reflection.h:365:8: error: definition of implicit copy
constructor for 'pointer_inside_vector<flatbuffers::Table, unsigned char>'
is deprecated because it has a user-declared copy assignment operator
[-Werror,-Wdeprecated-copy]
void operator=(const pointer_inside_vector &piv);
^
It's unclear why the old code wanted to declare a public `operator=`
without defining it; that just seems like a misunderstanding of the C++03 idiom
for deleting a member function. And anyway, we don't *want* to delete the
assignment operator; these are polymorphic types that do not follow value
semantics and nobody should ever be trying to copy them. So the simplest fix
is just to go back to the Rule of Zero: remove the declaration of `operator=`
and let the compiler do what it wanted to do originally anyway.
"The best code is no code."
Also, update the generated .h files.
Fixes#5649.
Previously UnPack would allocate data with new and assign it to a
raw pointer. This behavior makes it possible for the pointer to be
leaked in case of OOM. This commit defaults to use the user specified
pointer (which needs to implement a move constructor, a .get() and a
.release() operators), thus preventing these leaks.
* Add Builder and Table typedefs
This gives us a way to use templates to go from a builder to a table
and back again without having to pass both types in.
* Fix tests/cpp17/generated_cpp17/monster_test_generated.h
* Add flatc '--cpp_std' switch and sandbox for C++17 code generator
- Added 'flac --cpp_std legacy' for compatibility with old compilers (VS2010);
- Added experimental switch 'flac --cpp_std c++17' for future development;
- Added C++17 sandbox test_cpp17.cpp;
- C++ code generator generates enums with explicit underlying type to avoid problems with the forward and backward schema compatibility;
- Adjusted CMakeLists.txt, CI and generate code scripts to support of introduced '--cpp_std';
* Fix --cpp_std values: c++0x, c++11, c++17
* Add 'cpp::CppStandard' enum
* Add testing engine into test_cpp17
* Rebase to upstream/master
* Set default '--cpp-std C++0x'
* Fix code generation (--cpp_std C++11) in CMakeLists.txt
- Fix dependency declaration of grpctest target
* Revert --cpp-std for the tests from explicit C++11 to flatc default value (C++0x)
* Fix C/C++ Create<Type>Direct with sorted vectors
If a struct has a key the vector has to be sorted. To sort the vector
you can't use "const".
* Changes due to code review
* Improve code readability
* Added a cpp UnPackSizePrefixed<struct_name> generated helper function
Missing helper function added to the cpp API generator for unpacking size prefixed structures
* Added generated test files
- update C++ monster_test::Color to unsigned type
- update Go Color:ubyte in the go_test.go
- add workaround for unsigned enum in java test
- sync generate.bat and generate.sh
Multiple calls of e.g. CreateString inside a call to a CreateTable
could cause those strings to end up in different locations in the
wire format, since order or argument evaluation is undefined.
This is allowed by the FlatBuffer format, but it is not helpful,
especially when debugging the contents of binaries, or comparing
against a "golden" binary for tests etc.
Now making sure that all the CreateTableDirect calls first serialize
sub strings/vectors before calling CreateTable.
Also made similar changes to the serialization of "binary schemas".

Some generic C++ and Rust code is not generated when unions use type
aliases because of potential ambiguity. Actually check for this
ambiguity and only disable offending code only if it is found.
Give the vtable offset enum inside each table the name
"FlatBuffersVTableOffset" and base type voffset_t so it can be used as a
dependent type in IsFieldPresent. This makes that function slightly
safer since it prevents calling it with arbitrary, non-table types.
Now, the only way to use IsFieldPresent incorrectly is to create your
own type which does not inherit from flatbuffers::Table but has a
dependent voffset convertible type "FlatBuffersVTableOffset".
Make an out-of-bounds check for enum values before using them to index the
names array. For consistency with non-sparse enums an empty string is
returned.
Fixes#4821
armeabi support was removed from the Android NDK so we should no
longer build it. Since this fixes the Android build failures this
commit also re-enables Travis Android builds.
While re-enabling Android builds, some recent changes broke C++98
support so this fixes those issues as well which include:
- Conditionally compiling use of move constructors, operators and
std::move.
- Changing sample to use flatbuffers::unique_ptr rather than
std::unique_ptr.
Finally, added the special "default_ptr_type" value for the
"cpp_ptr_type" attribute. This expands to the value passed to
the "--cpp-ptr-type" argument of flatc.
* Add operator== for c++ genated code
New "--gen-compare" option for flatc to generate compare operators. The operators are defined based on object based api types.
Inspired by issue #263.
* Improve compare operator for c++.
Thanks for the code review.
- Improve robustness against future schema extensions
- Code style
- Fix --rust generation in generate_code.sh
* added intended use-cases to monster_test.fbs
* added check for `cpp_ptr_type` on hashed fields
added default value 'naked' to `cpp_ptr_type` on hashed fields
* added C++ generation of cpp_type vectors
removed ctor call for vector fields
added condition !vector for cpp_type check
added Pack() and UnPack() code generation for vector of hashes
added generation of correct resolve/rehash for cpp_type elements
* added attribute 'cpp_ptr_type_get' to hold accessor for pointer types possible where '.get()' does not work
use case: cpp_ptr_type:"std::weak_ptr", cpp_ptr_type_get:".lock().get()"
* run flatc to re-generate headers
* added bool param is_ctor to GetDefaultScalarValue() to differentiate between usage places
* modified monster_test.fbs to remove usage of shared_ptr/weak_ptr
reason: STLport does not support std::shared_ptr and std::weak_ptr
* run flatc again to re-generate headers
* fixed symbol unique_ptr not in namespace std when building with STLport
* added support for parsing hash on vector elements
reversed check for scalar to check for vector
added C++ generation of cpp_type vectors
removed ctor call for vector fields
added condition !vector for cpp_type check
added Pack() and UnPack() code generation for vector of hashes
* schema change:
added table Referrable and weak references towards it from Monster
added single_weak_reference to Monster table
changed order with vector_of_weak_references
* re-generated monster schema dependent code
added Referrable.cs to FlatBuffers.Test.csproj
It was missing some helpers when we choose to use
size prefixed FlatBuffers.
* Add general helper : GetPrefixedSize
* Add generated helpers :
* GetSizePrefixedXXX
* VerfifySizePrefixedXXXBuffer
* FinishSizePrefixedXXXBuffer
* 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());
* c++: mini_reflect: update generated code
* Ensure types and names are set for mini_reflect
* c++: mini_refelct: update unit tests with new typed TypeTable
* Adding PR feedback of sylte and naming convention
* Remove copy constructor to make flatbuffers struct trivially copyable + add tests.
* Add support non c++11 compliant compilers.
* Fix std::trivially_copyiable test for non-C++11 compliant compilers.
* Fix trivially_copyable not part of glibc < 5 even with c++11 switch enabled.
