Package 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);
