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.

0.9.7
