public class DataOutputBufferFixed
extends DataOutputBuffer

An implementation of the DataOutputStream interface using a FastByteArrayOutputStream and exposing its buffer so copies can be avoided. This version does not expand if it runs out of capacity and throws BufferOverflowException instead. This class is completely thread unsafe.
