Package Summary  Overview Summary

class:AbstractQueuedLongSynchronizer.ConditionObject [NONE]

  • All Implemented Interfaces:
    Serializable, Condition
    Enclosing class:
    AbstractQueuedLongSynchronizer

    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.

    Since:
    1.6

constructor:<init>() [NONE]

  • ConditionObject

    public ConditionObject()
    Creates a new ConditionObject instance.

method:signal() [NONE]

method:signalAll() [NONE]

method:awaitUninterruptibly() [NONE]

method:await() [NONE]

method:awaitNanos(long) [NONE]

  • awaitNanos

    public final long awaitNanos​(long nanosTimeout)
                          throws InterruptedException
    
    Implements timed condition wait.
    1. If current thread is interrupted, throw InterruptedException.
    2. Save lock state returned by AbstractQueuedLongSynchronizer.getState().
    3. Invoke AbstractQueuedLongSynchronizer.release(long) with saved state as argument, throwing IllegalMonitorStateException if it fails.
    4. Block until signalled, interrupted, or timed out.
    5. Reacquire by invoking specialized version of AbstractQueuedLongSynchronizer.acquire(long) with saved state as argument.
    6. If interrupted while blocked in step 4, throw InterruptedException.
    Specified by:
    awaitNanos in interface Condition
    Parameters:
    nanosTimeout - the maximum time to wait, in nanoseconds
    Returns:
    an estimate of the nanosTimeout value minus the time spent waiting upon return from this method. A positive value may be used as the argument to a subsequent call to this method to finish waiting out the desired time. A value less than or equal to zero indicates that no time remains.
    Throws:
    InterruptedException - if the current thread is interrupted (and interruption of thread suspension is supported)

method:awaitUntil(java.util.Date) [NONE]

  • awaitUntil

    public final boolean awaitUntil​(Date deadline)
                             throws InterruptedException
    
    Implements absolute timed condition wait.
    1. If current thread is interrupted, throw InterruptedException.
    2. Save lock state returned by AbstractQueuedLongSynchronizer.getState().
    3. Invoke AbstractQueuedLongSynchronizer.release(long) with saved state as argument, throwing IllegalMonitorStateException if it fails.
    4. Block until signalled, interrupted, or timed out.
    5. Reacquire by invoking specialized version of AbstractQueuedLongSynchronizer.acquire(long) with saved state as argument.
    6. If interrupted while blocked in step 4, throw InterruptedException.
    7. If timed out while blocked in step 4, return false, else true.
    Specified by:
    awaitUntil in interface Condition
    Parameters:
    deadline - the absolute time to wait until
    Returns:
    false if the deadline has elapsed upon return, else true
    Throws:
    InterruptedException - if the current thread is interrupted (and interruption of thread suspension is supported)

method:await(long,java.util.concurrent.TimeUnit) [NONE]

  • await

    public final boolean await​(long time,
                               TimeUnit unit)
                        throws InterruptedException
    
    Implements timed condition wait.
    1. If current thread is interrupted, throw InterruptedException.
    2. Save lock state returned by AbstractQueuedLongSynchronizer.getState().
    3. Invoke AbstractQueuedLongSynchronizer.release(long) with saved state as argument, throwing IllegalMonitorStateException if it fails.
    4. Block until signalled, interrupted, or timed out.
    5. Reacquire by invoking specialized version of AbstractQueuedLongSynchronizer.acquire(long) with saved state as argument.
    6. If interrupted while blocked in step 4, throw InterruptedException.
    7. If timed out while blocked in step 4, return false, else true.
    Specified by:
    await in interface Condition
    Parameters:
    time - the maximum time to wait
    unit - the time unit of the time argument
    Returns:
    false if the waiting time detectably elapsed before return from the method, else true
    Throws:
    InterruptedException - if the current thread is interrupted (and interruption of thread suspension is supported)

method:hasWaiters() [NONE]

method:getWaitQueueLength() [NONE]

method:getWaitingThreads() [NONE]
