com.zanox.rabbiteasy.consumer.MessageConsumer
A simple implementation of a message consumer which implements rarely used handles by logging them and providing a convenient method to handle delivered messages. @author christian.bick @author uwe.janner @author soner.dastan
de.willuhn.jameica.messaging.MessageConsumer
io.vertx.core.eventbus.MessageConsumer
An event bus consumer object representing a stream of message to an {@link EventBus} address that canbe read from.
The {@link EventBus#consumer(String)} or {@link EventBus#localConsumer(String)}create a new consumer, the returned consumer is not yet registered against the event bus. Registration is effective after the {@link #handler(io.vertx.core.Handler)} method is invoked.
The consumer is unregistered from the event bus using the {@link #unregister()} method or by calling the{@link #handler(io.vertx.core.Handler)} with a null value.. @author Nick Scavelli

org.jacorb.notification.interfaces.MessageConsumer
The interface MessageConsumer provides an abstraction of an ProxySupplier.
The MessageConsumer is responsible to maintain the Connection to the real Consumer. To deliver a Message the MessageConsumer converts the Message to the appropiate Format (Any, StructuredEvent, Sequence of StructuredEvent) required by its Consumer and delivers it.

org.objectweb.joram.client.jms.MessageConsumer
Implements the javax.jms.MessageConsumer interface.
A client uses a MessageConsumer object to receive messages from a destination. A MessageConsumer object is created by calling the createConsumer method on a session object. A message consumer is normally dedicated to a unique destination.
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 the 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 must 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.

Examples of javax.jms.MessageConsumer

         // read the message from the queue


         Connection conn = cf.createConnection();
         conn.start();
         Session sess = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
         MessageConsumer cons = sess.createConsumer(queue);
         TextMessage tm = (TextMessage)cons.receive(5000);


         assertNotNull(tm);
         assertEquals(MESSAGE_TEXT, tm.getText());


         // the client VM should exit by itself. If it doesn't, that means we have a problem
