AtomicReference accumulateAndGet() method in Java with Examples
The accumulateAndGet() method of a AtomicReference class is used to atomically updates the current value of AtomicReference with the results of applying the given accumulatorFunction to the current and given values and returns the updated value. The accumulatorFunction should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads.
public final E accumulateAndGet(E x, BinaryOperator<E> accumulatorFunction)
Parameters: This method accepts:
- x which is the updated value and
- accumulatorFunction which is a side-effect-free function of two arguments.
Return value: This method returns the updated value.
