void await()
   throws InterruptedException
Causes the current thread to wait until it is signalled or interrupted.

The lock associated with this Condition is atomically released and the current thread becomes disabled for thread scheduling purposes and lies dormant until one of four things happens:

  • Some other thread invokes the signal() method for this Condition and the current thread happens to be chosen as the thread to be awakened; or
  • Some other thread invokes the signalAll() method for this Condition; or
  • Some other thread interrupts the current thread, and interruption of thread suspension is supported; or
  • A "spurious wakeup" occurs

In all cases, before this method can return the current thread must re-acquire the lock associated with this condition. When the thread returns it is guaranteed to hold this lock.

If the current thread:

  • has its interrupted status set on entry to this method; or
  • is interrupted while waiting and interruption of thread suspension is supported,
then InterruptedException is thrown and the current thread's interrupted status is cleared. It is not specified, in the first case, whether or not the test for interruption occurs before the lock is released.
There are other await() methods with slightly different signatures, including the use of timeouts.  See the Condition javadocs for more detail.
