ConcurrentSkipListMap.ComputeIfPresent(Object, IBiFunction) Method

Definition

If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.

[Android.Runtime.Register("computeIfPresent", "(Ljava/lang/Object;Ljava/util/function/BiFunction;)Ljava/lang/Object;", "GetComputeIfPresent_Ljava_lang_Object_Ljava_util_function_BiFunction_Handler", ApiSince=24)]
public virtual Java.Lang.Object? ComputeIfPresent (Java.Lang.Object? key, Java.Util.Functions.IBiFunction? remappingFunction);
[<Android.Runtime.Register("computeIfPresent", "(Ljava/lang/Object;Ljava/util/function/BiFunction;)Ljava/lang/Object;", "GetComputeIfPresent_Ljava_lang_Object_Ljava_util_function_BiFunction_Handler", ApiSince=24)>]
abstract member ComputeIfPresent : Java.Lang.Object * Java.Util.Functions.IBiFunction -> Java.Lang.Object
override this.ComputeIfPresent : Java.Lang.Object * Java.Util.Functions.IBiFunction -> Java.Lang.Object

Parameters

key
Object

key with which a value may be associated

remappingFunction
IBiFunction

the function to compute a value

Returns

the new value associated with the specified key, or null if none

Attributes

Remarks

If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value. The function is <em>NOT</em> guaranteed to be applied once atomically.
