returnValue = instance.Map(mapFunc)

C++

public:
generic<typename TResult>
where TResult : value class, gcnew()
Nullable<TResult> Map(
	NullableReadOnlySpanPairTFirst, TSecondMapStructFunc<TResult>^ mapFunc
)

Parameters

mapFunc NullableReadOnlySpanPairTFirst, TSecondMapStructFuncTResult: The function to apply to the contained value.

Type Parameters

TResult: The result type of the map operation.

Return Value

NullableTResult
If the HasValue property is , the result of applying mapFunc to the Value property; otherwise, .

Remarks

The function mapFunc is only called if the HasValue property is .
