Reference

Definition

Namespace:: Java.Util.Concurrent.Atomic

Assembly:: Mono.Android.dll

Important

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

[Android.Runtime.Register("weakCompareAndSet", "(Ljava/lang/Object;Ljava/lang/Object;ZZ)Z", "GetWeakCompareAndSet_Ljava_lang_Object_Ljava_lang_Object_ZZHandler")]
public virtual bool WeakCompareAndSet (Java.Lang.Object? expectedReference, Java.Lang.Object? newReference, bool expectedMark, bool newMark);

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

Parameters

expectedReference: Object

the expected value of the reference

newReference: Object

the new value for the reference

expectedMark: Boolean

the expected value of the mark

newMark: Boolean

the new value for the mark

Returns

Boolean

true if successful

Attributes: RegisterAttribute

Remarks

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