Detailed Description

template<typename Allocator = CrtAllocator>
struct GenericMemoryBuffer< Allocator >

Represents an in-memory output byte stream.

This class is mainly for being wrapped by EncodedOutputStream or AutoUTFOutputStream.

It is similar to FileWriteBuffer but the destination is an in-memory buffer instead of a file.

Differences between MemoryBuffer and StringBuffer:

1. StringBuffer has Encoding but MemoryBuffer is only a byte buffer.
2. StringBuffer::GetString() returns a null-terminated string. MemoryBuffer::GetBuffer() returns a buffer without terminator.

Template Parameters

Allocator

type for allocating memory buffer.

Note

implements Stream concept
