Class AbstractQueuedSynchronizer.ConditionObject

  • All Implemented Interfaces:
    Serializable, Condition
    Enclosing class:

    public class AbstractQueuedSynchronizer.ConditionObject
    extends Object
    implements Condition, Serializable
    Condition implementation for a AbstractQueuedSynchronizer serving as the basis of a Lock implementation.

    Method documentation for this class describes mechanics, not behavioral specifications from the point of view of Lock and Condition users. Exported versions of this class will in general need to be accompanied by documentation describing condition semantics that rely on those of the associated AbstractQueuedSynchronizer.

    This class is Serializable, but all fields are transient, so deserialized conditions have no waiters.
