Reference

Definition

Namespace:: Java.Util.Concurrent.Atomic

Assembly:: Mono.Android.dll

Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

Atomically sets the value of both the reference and stamp to the given update values if the current reference is == to the expected reference and the current stamp is equal to the expected stamp.

[Android.Runtime.Register("weakCompareAndSet", "(Ljava/lang/Object;Ljava/lang/Object;II)Z", "GetWeakCompareAndSet_Ljava_lang_Object_Ljava_lang_Object_IIHandler")]
public virtual bool WeakCompareAndSet (Java.Lang.Object? expectedReference, Java.Lang.Object? newReference, int expectedStamp, int newStamp);

[<Android.Runtime.Register("weakCompareAndSet", "(Ljava/lang/Object;Ljava/lang/Object;II)Z", "GetWeakCompareAndSet_Ljava_lang_Object_Ljava_lang_Object_IIHandler")>]
abstract member WeakCompareAndSet : Java.Lang.Object * Java.Lang.Object * int * int -> bool
override this.WeakCompareAndSet : Java.Lang.Object * Java.Lang.Object * int * int -> bool

Parameters

expectedReference: Object

the expected value of the reference

newReference: Object

the new value for the reference

expectedStamp: Int32

the expected value of the stamp

newStamp: Int32

the new value for the stamp

Returns

Boolean

true if successful

Attributes: RegisterAttribute

Remarks

Atomically sets the value of both the reference and stamp to the given update values if the current reference is == to the expected reference and the current stamp is equal to the expected stamp. This operation may fail spuriously and does not provide ordering guarantees, so is only rarely an appropriate alternative to compareAndSet.
