Alle implementierten Schnittstellen:: Serializable, Lock, IManagedContainerProvider, INotifier, IDeactivateable, ILifecycle

public class DelegableReentrantLock extends NonFairReentrantLock implements ILifecycle, IManagedContainerProvider

A reentrant lock that can be delegated to other threads as detected by delegate detectors.

Delegate detectors can be registered programmatically or discovered in a managed container. The plugin container is used by default.

This class implements ILifecycle and must be activated before use. As a consequence, it also implements INotifier, but it does not send any events.
