Interface RemoteCommitProvider

All Superinterfaces:

Closeable

All Known Implementing Classes:

AbstractRemoteCommitProvider, JMSRemoteCommitProvider, SingleJVMRemoteCommitProvider, TCPRemoteCommitProvider

public interface RemoteCommitProvider
extends Closeable

An entity that is responsible for communicating commit notification to other RemoteCommitEventManagers. Each event manager creates a remote commit provider, based on the values of the openjpa.RemoteCommitProvider configuration property. An adapter that implements TransactionListener is registered with each Broker. This adapter invokes broadcast, which is responsible for notifying other remote commit provider objects of the commit changes. Upon receiving a notification from a different remote commit provider, a provider must notify all local remote commit listeners via the RemoteCommitEventManager.fireEvent(java.lang.Object, java.lang.Object) method. A remote commit provider must not fire remote events for commits that originated with a local broker.
