AbstractQueuedSynchronizer.getState()
AbstractQueuedSynchronizer.release(int)

AbstractQueuedSynchronizer.getState()
AbstractQueuedSynchronizer.release(int)
with
saved state as argument, throwing
IllegalMonitorStateException if it fails.
AbstractQueuedSynchronizer.acquire(int)
with saved state as argument.
InterruptedException
- if the current thread is interrupted
(and interruption of thread suspension is supported)public final long awaitNanos(long nanosTimeout) throws InterruptedException
AbstractQueuedSynchronizer.getState()
AbstractQueuedSynchronizer.release(int)
with
saved state as argument, throwing
IllegalMonitorStateException if it fails.
AbstractQueuedSynchronizer.acquire(int)
with saved state as argument.
awaitNanos
in interface Condition
nanosTimeout
- the maximum time to wait, in nanoseconds
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.
InterruptedException
- if the current thread is interrupted
(and interruption of thread suspension is supported)public final boolean awaitUntil(Date deadline) throws InterruptedException
AbstractQueuedSynchronizer.getState()
AbstractQueuedSynchronizer.release(int)
with
saved state as argument, throwing
IllegalMonitorStateException if it fails.
AbstractQueuedSynchronizer.acquire(int)
with saved state as argument.
awaitUntil
in interface Condition
deadline
- the absolute time to wait until
false
if the deadline has elapsed upon return, else
true
InterruptedException
- if the current thread is interrupted
(and interruption of thread suspension is supported)public final boolean await(long time, TimeUnit unit) throws InterruptedException
AbstractQueuedSynchronizer.getState()
AbstractQueuedSynchronizer.release(int)
with
saved state as argument, throwing
IllegalMonitorStateException if it fails.
AbstractQueuedSynchronizer.acquire(int)
with saved state as argument.
time
- the maximum time to waitunit
- the time unit of the time
argument
false
if the waiting time detectably elapsed
before return from the method, else true
InterruptedException
- if the current thread is interrupted
(and interruption of thread suspension is supported)protected final boolean hasWaiters()
