Class PduFactory

java.lang.Object
  edu.nps.moves.disutil.PduFactory

public class PduFactory
extends java.lang.Object

Simple factory for PDUs. When bytes are received on the wire, they're passed off to us and the correct constructor called to return the correct PDU type.

This should be reworked to use the separate enumerations package, which is generated from the XML EBV file. That's included with the open-dis distribution, but it's still a little new.
