org.jboss.messaging.core.message.Message
A message is a routable instance that has a payload. The payload is opaque to the messaging system. When implementing this interface, make sure you override equals() and hashCode() such that two Message instances with equals IDs are equal. @author Ovidiu Feodorov @author Tim Fox @version $Revision: 2202 $ $Id: Message.java 2202 2007-02-08 10:50:26Z timfox $
