org.jboss.messaging.core.contract.Replicator
A Replicator This is used for replicating arbitrary data across a cluster. Data is structured as follows: There is an arbitrary key to identify the data, e.g. the connection factory name Then, for that key, there is an entry for each node id. @author Tim Fox @author Ovidiu Feodorov @version $Revision: 2868 $ $Id: Replicator.java 2868 2007-07-10 20:22:16Z timfox $
