[Android.Runtime.Register("getAndAccumulate", "(ILjava/lang/Object;Ljava/util/function/BinaryOperator;)Ljava/lang/Object;", "", ApiSince=24)]
public Java.Lang.Object? GetAndAccumulate (int i, Java.Lang.Object? x, Java.Util.Functions.IBinaryOperator? accumulatorFunction);

[<Android.Runtime.Register("getAndAccumulate", "(ILjava/lang/Object;Ljava/util/function/BinaryOperator;)Ljava/lang/Object;", "", ApiSince=24)>]
member this.GetAndAccumulate : int * Java.Lang.Object * Java.Util.Functions.IBinaryOperator -> Java.Lang.Object

Parameters

i: Int32

the index

x: Object

the update value

accumulatorFunction: IBinaryOperator

a side-effect-free function of two arguments

Returns

Object

the previous value

Attributes: RegisterAttribute

Remarks

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 the previous 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.
