↳ | java.util.concurrent.locks.AbstractQueuedSynchronizer.ConditionObject |
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.

the desired time. A value less than or equal to zero
indicates that no time remains.InterruptedException |
