Interface MessageListener

public interface MessageListener

Allows a listener to be notified when a message arrives. Contrary to the pull-style of channels, some building blocks (e.g., 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.
