  4. final def accumulateAndGet(x: Long, accumulatorFunction: LongBinaryOperator): Long

    Atomically updates (with memory effects as specified by VarHandle#compareAndSet) the current value with the results of applying the given function to the current and given values, returning the updated value.

    Atomically updates (with memory effects as specified by VarHandle#compareAndSet) the current value with the results of applying the given function to the current and given values, returning the updated value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. The function is applied with the current value as its first argument, and the given update as the second argument.

    x
