Package org.jgroups
Interface ExtendedMessageListener
- All Superinterfaces:
MessageListener
- All Known Subinterfaces:
ExtendedReceiver
- All Known Implementing Classes:
DistributedHashtable
,Draw
,ExtendedReceiverAdapter
,MessageListenerAdapter
,ReplicatedHashMap
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)
