Detailed Description

An output stream that writes to a Buffer.

The benefit of using stream interface is that it provides automatic buffering of written data and eliminates (or reduces) overhead of resizing the underlying buffer when writing small pieces of data.

Usage example:

OBufferStream obuf;
obuf << "foo";
obuf.put(0);
obuf.write(anotherBuffer, anotherBufferSize);
std::shared_ptr<Buffer> buf = obuf.buf();
