-//! 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.
-
- \tparam Allocator type for allocating memory buffer.
- \note implements Stream concept
