AtomicLong.GetAndAccumulate(Int64, ILongBinaryOperator) Method

Definition

Namespace:

Java.Util.Concurrent.Atomic

Assembly:

Mono.Android.dll

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 previous value.

[Android.Runtime.Register("getAndAccumulate", "(JLjava/util/function/LongBinaryOperator;)J", "", ApiSince=24)]
public long GetAndAccumulate (long x, Java.Util.Functions.ILongBinaryOperator? accumulatorFunction);

[<Android.Runtime.Register("getAndAccumulate", "(JLjava/util/function/LongBinaryOperator;)J", "", ApiSince=24)>]
member this.GetAndAccumulate : int64 * Java.Util.Functions.ILongBinaryOperator -> int64

Parameters

x

Int64

the update value

accumulatorFunction

ILongBinaryOperator

a side-effect-free function of two arguments

Returns

Int64

the previous value

Attributes

RegisterAttribute

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 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 as its first argument, and the given update as the second argument.
