org.apache.openjpa.event
Interface RemoteCommitListener

All Superinterfaces:

Closeable

All Known Implementing Classes:

ConcurrentDataCache, ConcurrentQueryCache, PartitionedDataCache

public interface RemoteCommitListener
extends Closeable

An entity that wishes to be notified when Brokers associated with remote BrokerFactories commit. A RemoteCommitListener is not notified of commits that originated with a Broker created from the BrokerFactory that it is registered with. (Of course, if a listener is registered with multiple factories, this situation might be complicated a bit.) Usage:

 import org.apache.openjpa.event.*;
 import org.apache.openjpa.conf.*;
 
 OpenJPAConfiguration conf =
         factory.getConfiguraiton ();
  RemoteCommitListener l = new RemoteCommitListener () {
 public void afterCommit (RemoteCommitEvent e) {
 // update a Swing widget when remote brokers make
 // changes to reference data }
  public void close () { } };
  conf.getRemoteCommitEventManager ().addListener (l);
