I updated idl_gen_general.cpp to add support for generating a Get Bytes
method for a vector to the generated C# source code. Given a byte vector
field named Foo, a method named GetFooBytes() will be generated in the
C# source code that will return an ArraySegment<byte> value referencing
the vector data in the underlying ByteBuffer.
I added a method to Table.cs named __vector_as_arraysegment that is used
by the code generated by the change to the C# generator.
__vector_as_arraysegment will take the offset of the vector and will
return the ArraySegment<byte> value corresponding to the bytes that
store the vector data.
I updated FlatBuffersExampleTests.cs to add tests to validate my
implementation of Table.__vector_as_arraysegment. I added tests to
demonstrate that the bytes for the monster's name can be extracted from
the underlying byte array. I also added tests to show that
Table.__vector_as_arraysegment returns a null value if the vector is not
present in the FlatBuffer.
I used the updated flatc.exe program to regenerate the C# source files
for the MyGame example. The new Monster class includes the GetXXXBytes
methods to return the byte arrays containing data for vectors.
Fixes a bug where the logic to determine when to use a C# enum flags
both enums and vectors of enums. This causes the C# generator to
generate code that doesn't compile for tables that contain vectors of
enums.
The fix also consolidates type generation functions a bit and adds
some additional casting functions for clarity.

Currently, we do not register this library to packagist as still experimental and versioning problem.
If you intended to use flatbuffers with composer. add repostiories section to composer.json like below.
"repositories": [{
"type": "vcs",
"url": "https://github.com/google/flatbuffers"
}],
and just put google/flatbuffers.
"require": {
"google/flatbuffers": "*"
}
* PHP's integer is platform dependant. we strongly recommend use 64bit machine
and don't use uint, ulong types as prevent overflow issue.
ref: http://php.net/manual/en/language.types.integer.php
* php don't support float type. floating point numbers are always parsed as double precision internally.
ref: http://php.net/manual/en/language.types.float.php
* ByteBuffer is little bit slow implemnentation due to many chr/ord function calls. Especially encoding objects.
This is expected performance as PHP5 has parsing arguments overhead. probably we'll add C-extension.
Basically, PHP implementation respects Java and C# implementation.
Note: ByteBuffer and FlatBuffersBuilder class are not intended to use other purposes.
we may change internal API foreseeable future.
PSR-2, PSR-4 standards.
Implemented simple assertion class (respect JavaScript testcase implementation) as we prefer small code base.
this also keeps CI iteration speed.
we'll choose phpunit or something when the test cases grown.
When creating a CreateXxx(...) method for a simple table type,
enum-type fields with a non-zero default must have an explicit
cast for the respective argument default value, because in C#,
there is an implicit cast from int to an enum only for 0.
Also, added an example of such type into the example monster_test
type, so that we test this feature.
Implement code generation and self-contained runtime library for Python.
The test suite verifies:
- Correctness of generated Python code by comparing output to that of
the other language ports.
- The exact bytes in the Builder buffer during many scenarios.
- Vtable deduplication correctness.
- Edge cases for table construction, via a fuzzer derived from the Go
implementation.
- All code is simultaneously valid in Python 2.6, 2.7, and 3.4.
The test suite includes benchmarks for:
- Building 'gold' data.
- Parsing 'gold' data.
- Deduplicating vtables.
All tests pass on this author's system for the following Python
implementations:
- CPython 2.6.7
- CPython 2.7.8
- CPython 3.4.2
- PyPy 2.5.0 (CPython 2.7.8 compatible)
When accessing a union field, we should return the same object type
as was given to the method, i.e. the parameter should have a generic
type for any Table-derived type. This way, we do not need to make
superfluous casts (which also reduce type safety) like
var myUnionType = (MyUnionType)buff.GetUnionField(new MyUnionType());
when we can do just
var myUnionType = buff.GetUnionField(new MyUnionType());

In C#, plain field accessors should not be nonparametric methods
but should be standard property getters.
The accessor methods with parameters were renamed to `GetXxx`
because a method cannot be named identically to a property.
Also, `ByteBuffer.Position`, `FlatBufferBuilder.Offset` and
`FlatBufferBuilder.DataBuffer` are now properties instead
of nonparametric accessor methods, for more idiomatic C# style.
This is a breaking change, all client C# code accessing these
fields needs to be changed (i.e. remove those `()` or add the
`Get` prefix).

Enums should not be (badly) emulated with classes in C# but should
use native C# enums instead. Java implementation made an explicit
choice not to use the (more complex) Java enums, but C# enums are
just light-weight syntactic coating over integral types.
Fixes issue #171.
Change-Id: I9f4d6ba5324400a1e52982e49b58603cb7d7cca7
Tested by regenerating all tests/ generated sources; note that only
Monster.java changes. Ran flattests as well.
Change-Id: I65b6ea7d208b0ccd6a0b34761162fed6ba391fc5
(Java doesn't support unsigned types).
ubyte/ushort return as int
uint returns as long
(all with correct masking)
ulong still returns as long, as before.
Tested: on Linux & Windows.

getRootAs..() function now has a second implementation that
accepts an existing object to allow object reuse, much like
all other methods that refer to objects.

Also fixed Go unit tests not being up to date with recent schema
changes.
