  4. final def accumulateAndGet(i: Int, x: E, accumulatorFunction: BinaryOperator[E]): E

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

    Atomically updates (with memory effects as specified by VarHandle#compareAndSet) the element at index i with the results of applying the given function to the current and given values, returning tnewNexthe 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 of the element at index i as its first argument, and the given update as the second argument.
