Definition

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.

[Android.Runtime.Register("accumulateAndGet", "(Ljava/lang/Object;Ljava/util/function/BinaryOperator;)Ljava/lang/Object;", "", ApiSince=24)]
public Java.Lang.Object? AccumulateAndGet (Java.Lang.Object? x, Java.Util.Functions.IBinaryOperator? accumulatorFunction);
[<Android.Runtime.Register("accumulateAndGet", "(Ljava/lang/Object;Ljava/util/function/BinaryOperator;)Ljava/lang/Object;", "", ApiSince=24)>]
member this.AccumulateAndGet : Java.Lang.Object * Java.Util.Functions.IBinaryOperator -> Java.Lang.Object

Parameters

x
Object

the update value

accumulatorFunction
IBinaryOperator

a side-effect-free function of two arguments

the updated value

Attributes

Remarks

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.
