| org.jgroups.ExtendedMessageListener
All known Subclasses: org.jgroups.demos.Chat, org.jgroups.blocks.MessageListenerAdapter,
| ExtendedMessageListener | | public interface ExtendedMessageListener extends MessageListener(Code) | | ExtendedMessageListener has additional callbacks for:
- partial state transfer - http://jira.jboss.com/jira/browse/JGRP-118
- streaming state transfer - http://jira.jboss.com/jira/browse/JGRP-89
Application channels interested in using streaming state transfer, beside
implementing this interface, have to be configured with
STREAMING_STATE_TRANSFER protocol rather than the default
STATE_TRANSFER protocol.
Note:
This interface will be merged with MessageListener in 3.0 (API changes)
