All Implemented Interfaces:

public class GSQueueSenderImpl
extends GSMessageProducerImpl

GigaSpaces implementation of the javax.jms.Session interface. A client uses a GSQueueSenderImpl object to send messages to a queue.

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

If the GSQueueSenderImpl 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 GSQueueSenderImpl. A MessageProducer object is recommended when creating new code. The GSQueueSenderImpl is provided to support existing code.
