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
Allocatortype for allocating memory buffer.
Note
implements Stream concept
