public class SimpleDataOutput
extends ByteOutputStream
implements DataOutput

A simple base implementation of DataOutput which wraps a ByteOutput. This implementation maintains an internal buffer.

Field Summary

protected byte[]	buffer The internal buffer.
protected int	bufferSize The size of the internal buffer.
