java.util.concurrent.atomic.AtomicBoolean.compareAndSet()
Atomically sets the value to the given updated value if the current value {@code ==} the expected value. @param expect the expected value @param update the new value @return {@code true} if successful. False return indicates thatthe actual value was not equal to the expected value.
