Package org.apache.openjpa.event

OpenJPA Events

This package provides some interfaces and useful implementations for OpenJPA's event notification framework. This framework allows efficient notification of object modifications and transaction changes.

Interface Summary

Interface	Description
AttachListener	Listener for when a detached instance is attached.
BeginTransactionListener	Notified when transactions begin.
BrokerFactoryListener	Interface for listening to BrokerFactoryEvent objects.
CallbackModes	Callback handling constants.
ClearListener	Listener for when persistent state is cleared from an instance.
DeleteListener	Listener for when a persistent instance is deleted.
DetachListener	Listener for when a persistent instance is detached.
DirtyListener	Listener for when a persistent instance becomes dirty.
EndTransactionListener	Notified when transactions end.
FlushTransactionListener	Notified on transaction flush.
LifecycleCallbacks	A lifecycle listener that responds to callbacks rather than events.
LifecycleEventManager.ListenerAdapter	Interface that facades to other lifecycle listener interfaces can implement to choose which events to respond to based on their delegate.
LifecycleListener	Interface for listening to all LifecycleEvents.
LoadListener	Listener for when state is loaded into a persistent instnace.
OrphanedKeyAction	Perform an action when OpenJPA detects an orphaned key in the database.
PersistListener	Listener for newly-persisted instances.
PostDeleteListener
PostPersistListener
RemoteCommitListener	An entity that wishes to be notified when Brokers associated with remote BrokerFactories commit.
RemoteCommitProvider	An entity that is responsible for communicating commit notification to other RemoteCommitEventManagers.
StoreListener	Listener for when persistent instances are stored to the database.
TransactionListener	Interface for listening to all TransactionEvents.
UpdateListener

Class Summary

Class	Description
AbstractLifecycleListener	Abstract implementation of the LifecycleListener interface which delegates events to a single method.
AbstractRemoteCommitProvider	Abstract implementation of RemoteCommitProvider.
AbstractTransactionListener	Abstract implementation of the TransactionListener interface that provides no-op implementations of all methods.
BeanLifecycleCallbacks	Performs a callback method on a cached bean instance.
BrokerFactoryEvent	Event fired when a BrokerFactory is created.
BrokerFactoryEventManager	EventManager responsible for notifying listeners of BrokerFactoryEvents.
DynamicTCPRemoteCommitProvider
ExceptionOrphanedKeyAction	Throw a ObjectNotFoundException when an orphaned key is discovered.
JMSRemoteCommitProvider	JMS-based implementation of RemoteCommitProvider that listens for object modifications and propagates those changes to other RemoteCommitProviders over a JMS topic.
LifecycleEvent	Lifecycle event on a persistent instance.
LifecycleEventManager	Manager that can be used to track and notify listeners on lifecycle events.
LifecycleEventManager.ListenerList	Extended list that tracks what event types its elements care about.
LogOrphanedKeyAction	Log a message when an orphaned key is discovered.
MethodLifecycleCallbacks	Callback adapter that invokes a callback method via reflection.
NoneOrphanedKeyAction	Does nothing when an orphaned key is discovered.
RemoteCommitEvent	Event type to hold the IDs of additions, updates, and deletes.
RemoteCommitEventManager	Manager that can be used to track and notify RemoteCommitListeners on remote commit events.
SingleJVMRemoteCommitProvider	Single-JVM-only implementation of RemoteCommitProvider that listens for object modifications and propagates those changes to other SingleJVMRemoteCommitProviders in the same JVM.
TCPRemoteCommitProvider	TCP-based implementation of RemoteCommitProvider that listens for object modifications and propagates those changes to other RemoteCommitProviders over TCP sockets.
TransactionEvent	A transactional event.
TransactionEventManager	Manager that can be used to track and notify transaction listeners of transaction-related events.
