Object API codegen which previously generated invalid code that wouldn't
compile.

- Nested structs would originally generate syntax errors due to adding an

- Fixed size arrays of nested structs would originally generate code for

4 years ago[ts] Fix empty source/dest namespaces when reexporting. (#5841)

[ts] Fix empty source/dest namespaces when reexporting. (#5841)

When either source or destination or both namespaces were empty, flatc
was generating incorrect TS code.

For example:

```
export namespace  {
export import ObjectId = NS10770172024577249292..ObjectId;}
```

In this case the target namespace is empty, and so is the namespace
between the NSxxx placeholder and the target type.

[Java][FlexBuffers] Optimize Map access (#5735)

The original implementation of map access is very naive:
- Encode String to UTF8 byte[]
- Creates a new KeyVector
- Performs a binary search to find the key
- return value

So every access to the Map there was useless allocations of Keys and KeyVector
and complete encoding of the search key, which for most comparisons would be wasteful.

This changes completely removes the use of KeyVector and compute the key
positions on the spot. Besides that, it compares keys codepoint-by-codepoint,
avoiding unnecessary allocations and reducing encoding for most cases.

Some benchmarks result in a 2.75x speedup.

FLATBUFFERS_ENABLE_PCH enable precompile headers support for 'flatbuffers' and 'flatc'. Default if OFF.
You need to set it to ON to make it work. 'cmake -DFLATBUFFERS_ENABLE_PCH=ON ..'

    include/flatbuffers/reflection.h:365:8: error: definition of implicit copy

          [-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.

[Java][FlexBuffers] Abstract buffer access from ByteBuffer (#5743)

To read and build flexbuffers on Java, one needs to wrap the data
using  ByteBuffer. But for the common case of having ByteBuffers
backed by arrays, accessing from a ByteBuffer might be inefficient.

So this change introduces two interfaces: ReadBuf and ReadWriteBuf.
It allows one to read and writes data directly on an array. It also allow
 other buffer implementations to be used with flexbuffers.

Another change is that FlexBuffersBuilder backed by array allows
the buffer to grow with the increase of the message size. Something
that could not be done with ByteBuffer.

4 years agoFlexBuffers: C++: scalar-only typed vectors were not aligned.

FlexBuffers: C++: scalar-only typed vectors were not aligned.

This means data written with older versions of this code has
potentially misaligned data, which we'll need to support.
This isn't a problem on most architectures, but could be on
older ARM chips. To support them properly may require swapping
out uses of `flatbuffers::ReadScalar` with a version that does a
memcpy internally.

* [Java][FlexBuffers] Deprecate typed vector strings due to design flaw

It will still be possible to read buffers with this type, but the
elements will be treated as FBT_KEY and will be read as null-terminated
string.

Trying to build a vector of strings as typed will throw an exception.

More information on https://github.com/google/flatbuffers/issues/5627

Also, fix another bug on strings, where long strings were not properly
aligned.

* [Java][FlexBuffers] Make FBT_VECTOR_STRING_DEPRECATED considered typed.

The logic for FlexBuffers.isVectorType() was changed
to not consider FBT_VECTOR_STRING_DEPRECATED a typed
vector, but that can lead to missinterpretation for
existing serialized data. So we are reverting.
