org.jboss.messaging.core.contract.MessageReference
A reference to a message. Channels store message references rather than the messages themselves. If many channels have contain the same reference this makes a lot of sense @author Ovidiu Feodorov @author Tim Fox @version $Revision: 3020 $ $Id: MessageReference.java 3020 2007-08-21 15:46:38Z timfox $
