Class FinalizingBrokerImpl

java.lang.Object

org.apache.openjpa.kernel.BrokerImpl

org.apache.openjpa.kernel.FinalizingBrokerImpl

All Implemented Interfaces:

jakarta.transaction.Synchronization, Serializable, Cloneable, CallbackModes, AutoClear, AutoDetach, Broker, ConnectionRetainModes, DetachState, FindCallbacks, LockLevels, RestoreState, StoreContext, Closeable

Direct Known Subclasses:

DistributedBrokerImpl

public class FinalizingBrokerImpl
extends BrokerImpl

Subtype of BrokerImpl that automatically closes itself during finalization. This implementation guards against potential resource leaks, but also incurs a scalability bottleneck as instances are enlisted in the finalization queue and subsequently cleaned up.

Since:

0.9.7
