Definition

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 updated value.

[Android.Runtime.Register("accumulateAndGet", "(IILjava/util/function/IntBinaryOperator;)I", "", ApiSince=24)]
public int AccumulateAndGet (int i, int x, Java.Util.Functions.IIntBinaryOperator? accumulatorFunction);
[<Android.Runtime.Register("accumulateAndGet", "(IILjava/util/function/IntBinaryOperator;)I", "", ApiSince=24)>]
member this.AccumulateAndGet : int * int * Java.Util.Functions.IIntBinaryOperator -> int

Parameters

i
Int32

the index

x
Int32

the update value

accumulatorFunction
IIntBinaryOperator

a side-effect-free function of two arguments

Returns

the updated value

Attributes

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 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.
