Class AbstractOwnableSynchronizer

  • All Implemented Interfaces:
    java.io.Serializable
    Direct Known Subclasses:
    AbstractQueuedLongSynchronizer, AbstractQueuedSynchronizer
    public abstract class AbstractOwnableSynchronizer
extends java.lang.Object
implements java.io.Serializable
    A synchronizer that may be exclusively owned by a strand. This class provides a basis for creating locks and related synchronizers that may entail a notion of ownership. The AbstractOwnableSynchronizer class itself does not manage or use this information. However, subclasses and tools may use appropriately maintained values to help control and monitor access and provide diagnostics.
