Performs atomic notifying operations.

If there is a thread blocked in atomic waiting operation (i.e. wait() ) on * this , then unblocks at least one such thread; otherwise does nothing.

Return value

(none)

Notes

This form of change-detection is often more efficient than simple polling or pure spinlocks.
