Class MessageBase

java.lang.Object

com.sun.corba.se.impl.protocol.giopmsgheaders.MessageBase

All Implemented Interfaces:

Message

Direct Known Subclasses:

Message_1_0, Message_1_1

public abstract class MessageBase
extends Object
implements Message

This class acts as the base class for the various GIOP message types. This also serves as a factory to create various message types. We currently support GIOP 1.0, 1.1 and 1.2 message types.
