java.lang.Object
- java.util.concurrent.locks.AbstractQueuedLongSynchronizer.ConditionObject

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

```
public AbstractQueuedLongSynchronizer.ConditionObject()
```
    Creates a new ConditionObject instance.
- Method Detail
  - signal
```
public final void signal()
```
    Moves the longest-waiting thread, if one exists, from the wait queue for this condition to the wait queue for the owning lock.
    
    Specified by:
    
    signal in interface Condition
    
    Throws:
    
    IllegalMonitorStateException - if AbstractQueuedLongSynchronizer.isHeldExclusively() returns false
  - signalAll
```
public final void signalAll()
```
    Moves all threads from the wait queue for this condition to the wait queue for the owning lock.
    
    Specified by:
    
    signalAll in interface Condition
    
    Throws:
    
    IllegalMonitorStateException - if AbstractQueuedLongSynchronizer.isHeldExclusively() returns false
  - awaitUninterruptibly
```
public final void awaitUninterruptibly()
```
    Implements uninterruptible condition wait.
    1. Save lock state returned by AbstractQueuedLongSynchronizer.getState().
    2. Invoke AbstractQueuedLongSynchronizer.release(long) with saved state as argument, throwing IllegalMonitorStateException if it fails.
    3. Block until signalled.
    4. Reacquire by invoking specialized version of AbstractQueuedLongSynchronizer.acquire(long) with saved state as argument.
    Specified by:
    
    awaitUninterruptibly in interface Condition
  - await
```
public final void await()
                 throws InterruptedException
```
    Implements interruptible 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 or interrupted.
    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:
    
    await in interface Condition
    
    Throws:
    
    InterruptedException - if the current thread is interrupted (and interruption of thread suspension is supported)
  - 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)
  - 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)
