Examples of MessageProxy

MessageProxy is a thin proxy for JBossMessage. JMS Users actually handle MessageProxy instances rather than JBossMessage instances. The purpose of this class and subclasses is to prevent unnecessary copying of a message. After a message is sent, the message can be changed, but this should not affect the sent message. This class accomplishes this by intercepting any methods which change the state of the message and copying either the headers, jms properties or body as appropriate. This enables up to make the minimum amount of copies while still preserving JMS semantics. Similarly on receive. See JMS1.1 Spec 3.9, 3.10 for more details. If nothing is changed, nothing is copied. @author Tim FoxMessageProxy.java,v 1.1 2006/03/08 08:00:34 timfox Exp
