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

Object
