Examples of java.util.concurrent.atomic.AtomicLongArray.compareAndSet()

java.util.concurrent.atomic.AtomicLongArray.compareAndSet()
Atomically sets the element at position {@code i} to the givenupdated value if the current value {@code ==} the expected value. @param i the index @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.

            // determine what the new long value will be after we set the appropriate bit.
            long currentLongValue = segment.get(longPosition);
            long newLongValue = currentLongValue | mask;


            // if no other thread has modified the value since we read it, we won the race and we are done.
            if(segment.compareAndSet(longPosition, currentLongValue, newLongValue))
                break;
        }
    }
