Class AbstractQueuedLongSynchronizer.ConditionObject

All Implemented Interfaces:
Serializable, Condition
Enclosing class:

public class AbstractQueuedLongSynchronizer.ConditionObject
extends Object
implements Condition, Serializable
Condition implementation for a AbstractQueuedLongSynchronizer 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 AbstractQueuedLongSynchronizer.

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