)

VB

Public Function Map(Of TResultFirst, TResultSecond) ( 
	mapFunc As NullableReadOnlySpanPairTFirst, TSecondMapReadOnlyFunc(Of TResultFirst, TResultSecond)
) As NullableReadOnlySpanPair(Of TResultFirst, TResultSecond)

Dim mapFunc As NullableReadOnlySpanPairTFirst, TSecondMapReadOnlyFunc(Of TResultFirst, TResultSecond)

Dim returnValue As NullableReadOnlySpanPair(Of TResultFirst, TResultSecond)

returnValue = instance.Map(mapFunc)

C++

public:
generic<typename TResultFirst, typename TResultSecond>
NullableReadOnlySpanPair<TResultFirst, TResultSecond> Map(
	NullableReadOnlySpanPairTFirst, TSecondMapReadOnlyFunc<TResultFirst, TResultSecond>^ mapFunc
)

Parameters

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

Type Parameters

TResultFirst: The type of the items in the first value of the resulting NullableReadOnlySpanPairTFirst, TSecond.
TResultSecond: The type of the items in the second value of the resulting NullableReadOnlySpanPairTFirst, TSecond.

Return Value

NullableReadOnlySpanPairTResultFirst, TResultSecond
If the HasValue property is , the result of applying mapFunc to the Value property; otherwise, an empty NullableReadOnlySpanPairTFirst, TSecond.

Remarks

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