/**
 * A client uses a QueueSender object to send messages to a
 * queue. 

*

* Normally, the Queue is specified when a QueueSender * * is created. In this case, an attempt to use the send methods * for an unidentified QueueSender will throw a * java.lang.UnsupportedOperationException. *

*

* If the QueueSender is created with an unidentified * Queue, * an attempt to use the send methods that assume that the * Queue has been identified will throw a * java.lang.UnsupportedOperationException. *

*

* During the execution of its send method, a message must not be * changed by other threads within the client. If the message is modified, the * result of the send is undefined.

*

* After sending a message, a client may retain and modify it without affecting * the message that has been sent. The same message object may be sent multiple * times.

*

* The following message headers are set as part of sending a message: * JMSDestination, JMSDeliveryMode,JMSExpiration,JMSPriority, * JMSMessageID and JMSTimeStamp. When the * message is sent, the values of these headers are ignored. After the * completion of the send, the headers hold the values specified * by the method sending the message. It is possible for the send * method not to set JMSMessageID and JMSTimeStamp * if the setting of these headers is explicitly disabled by the * MessageProducer.setDisableMessageID or * MessageProducer.setDisableMessageTimestamp method.

*

* Creating a MessageProducer provides the same features as * creating a QueueSender. A MessageProducer * object is recommended when creating new code. The QueueSender * is provided to support existing code. * * @see javax.jms.MessageProducer * @see javax.jms.QueueSession#createSender(Queue) */ public class ActiveMQQueueSender extends ActiveMQMessageProducer implements QueueSender { protected ActiveMQQueueSender(ActiveMQSession session, ActiveMQDestination destination,int sendTimeout) throws JMSException { super(session, session.getNextProducerId(), destination,sendTimeout); } /** * Gets the queue associated with this QueueSender. * * @return this sender's queue * @throws JMSException if the JMS provider fails to get the queue for this * QueueSender due to some internal error. */ public Queue getQueue() throws JMSException { return (Queue)super.getDestination(); } /** * Sends a message to a queue for an unidentified message producer.
