IMessageConsumer Interface

A client uses a IMessageConsumer object to receive messages from a destination. A IMessageConsumer object is created by passing a IDestination object to a message-consumer creation method supplied by a session.

IMessageConsumer 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 MessageEventHandler object with a message consumer. As messages arrive at the message consumer, it delivers them by calling the MessageEventHandler's onMessage method.

It is a client programming error for a MessageEventHandler to throw an exception.

For a list of all members of this type, see IMessageConsumer Members.
