Attempts to compute a new mapped value for the specified key based on its current mapped value (or false if there is no current mapping).

[Android.Runtime.Register("compute", "(ILjava/util/function/IntBinaryOperator;)Z", "GetCompute_ILjava_util_function_IntBinaryOperator_Handler", ApiSince=37)]
public virtual bool Compute(int key, Java.Util.Functions.IIntBinaryOperator function);

[<Android.Runtime.Register("compute", "(ILjava/util/function/IntBinaryOperator;)Z", "GetCompute_ILjava_util_function_IntBinaryOperator_Handler", ApiSince=37)>]
abstract member Compute : int * Java.Util.Functions.IIntBinaryOperator -> bool
override this.Compute : int * Java.Util.Functions.IIntBinaryOperator -> bool

Parameters

key: Int32

The key to compute the value for.

function: IIntBinaryOperator

The function to compute the new value. For the second argument that represents the current mapped value, 0 is used for false and 1 for true. The returned value will be converted to a boolean similarly, 0 for false and true otherwise.

Returns

Boolean

The new mapped value.

Attributes: RegisterAttribute

Remarks

Attempts to compute a new mapped value for the specified key based on its current mapped value (or false if there is no current mapping). The boolean values passed to and returned from the function are converted to integers (0 for false and true otherwise) to avoid type boxing.
