AtomicIntegerFieldUpdater.WeakCompareAndSet(Object, Int32, Int32) Method

Definition

Atomically sets the field of the given object managed by this updater to the given updated value if the current value == the expected value.

[Android.Runtime.Register("weakCompareAndSet", "(Ljava/lang/Object;II)Z", "GetWeakCompareAndSet_Ljava_lang_Object_IIHandler")]
public abstract bool WeakCompareAndSet (Java.Lang.Object? obj, int expect, int update);
[<Android.Runtime.Register("weakCompareAndSet", "(Ljava/lang/Object;II)Z", "GetWeakCompareAndSet_Ljava_lang_Object_IIHandler")>]
abstract member WeakCompareAndSet : Java.Lang.Object * int * int -> bool

Parameters

obj
Object

An object whose field to conditionally set

expect
Int32

the expected value

update
Int32

the new value

Returns

true if successful

Attributes

Remarks

Atomically sets the field of the given object managed by this updater to the given updated value if the current value == the expected value. This method is guaranteed to be atomic with respect to other calls to compareAndSet and set, but not necessarily with respect to other changes in the field.

This operation may fail spuriously and does not provide ordering guarantees, so is only rarely an appropriate alternative to compareAndSet.
