Detailed Description

Class implementing interface similar to ostringstream, but to construct ndn::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.put(0);
obuf.write(another_buffer, another_buffer_size);
shared_ptr<Buffer> buf = obuf.get();
