Interface MessageListener

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.
public byte[] getState()
Answers the group state; e.g., when joining.
Returns: byte[]
Called when a message is received.
Parameters: msg
public void setState(byte[] state)
Sets the group state; e.g., when joining.
Parameters: state
