Interface RemoteCommitListener

All Superinterfaces:

com.solarmetric.util.Closeable

All Known Implementing Classes:

DataCacheImpl, QueryCacheImpl

public interface RemoteCommitListener

extends com.solarmetric.util.Closeable

An entity that wishes to be notified when PersistenceManagers associated with remote PersistenceManagerFactories commit.

A RemoteCommitListener is not notified of commits that originated with a PersistenceManager created from the PersistenceManagerFactory that it is registered with. (Of course, if a listener is registered with multiple factories, this situation might be complicated a bit.)

Usage:

	import kodo.event.*;
	import kodo.conf.*;
	
	JDOConfiguration conf = 
		((KodoPersistenceManagerFactory) pmf).getConfiguraiton ();

	RemoteCommitListener l = new RemoteCommitListener () {
		public void afterCommit (RemoteCommitEvent e) {
			// update a Swing widget when remote PMs make 
			// changes to reference data
		}

		public void close () { }
	};
	
	conf.getRemoteCommitEventManager ().registerListener (l);
	

Since:

2.5.0
