DataStreamer

Overview

This provides the abstract base class streamers for serialization and deserialization of deltas and data in Data Abstract.

You will use one of the concrete implementations of this class (such as the BinDataStreamer in your application. You can also derive your own descendants of DataStreamer to implement a custom streaming format.
