Condition | 
Lock.newCondition()
Returns a new  
Condition instance that is bound to this
 Lock instance. | 
Condition | 
ReentrantReadWriteLock.ReadLock.newCondition()
Throws  
UnsupportedOperationException because
 ReadLocks do not support conditions. |

Returns an estimate of the number of threads waiting on the
 given condition associated with the write lock. 
 | 
boolean |
