Examples of ActiveMQMessageConsumer

org.activemq.ActiveMQMessageConsumer
A client uses a MessageConsumer object to receive messages from a destination. A MessageConsumer object is created by passing a Destination object to a message-consumer creation method supplied by a session.
MessageConsumer is the parent interface for all message consumers.
A message consumer can be created with a message selector. A message selector allows the client to restrict the messages delivered to the message consumer to those that match the selector.
A client may either synchronously receive a message consumer's messages or have the consumer asynchronously deliver them as they arrive.
For synchronous receipt, a client can request the next message from a message consumer using one of its receive methods. There are several variations of receive that allow a client to poll or wait for the next message.
For asynchronous delivery, a client can register a MessageListener object with a message consumer. As messages arrive at the message consumer, it delivers them by calling the MessageListener's onMessage method.
It is a client programming error for a MessageListener to throw an exception. @version $Revision: 1.1.1.1 $ @see javax.jms.MessageConsumer @see javax.jms.QueueReceiver @see javax.jms.TopicSubscriber @see javax.jms.Session
