Package com.swiftmq.jms

Class ObjectMessageImpl

java.lang.Object

com.swiftmq.jms.MessageImpl

com.swiftmq.jms.ObjectMessageImpl

All Implemented Interfaces:

java.io.Serializable, javax.jms.Message, javax.jms.ObjectMessage

public class ObjectMessageImpl
extends MessageImpl
implements javax.jms.ObjectMessage

Implementation of a ObjectMessage. There is one additional method getObject(classLoader) which must be used by Extension Swiftlet, passing their own classloader to construct the object. This is required due to hot deployment of Extension Swiftlets and different class loaders.
