| MessageListener | | public interface MessageListener (Code) | | Allows a listener to be notified when a message arrives.
Contrary to the pull-style of channels, some building blocks
(e.g.,
org.jgroups.blocks.PullPushAdapter ) provide an
event-like, push-style message delivery model.
In this case, the entity to be notified of message reception needs to
provide a callback to be invoked whenever a message has been received.
The MessageListener interface provides a method to do so.
