public Vector<U> MapWhere<U>(
	Func<T, bool> condition,
	Func<T, U> function
)

Visual Basic

Public Function MapWhere(Of U) ( 
	condition As Func(Of T, Boolean),
	function As Func(Of T, U)
) As Vector(Of U)

C++/CLI

public:
generic<typename U>
Vector<U>^ MapWhere(
	Func<T, bool>^ condition, 
	Func<T, U>^ function
)

member MapWhere : 
        condition : Func<'T, bool> * 
        function : Func<'T, 'U> -> Vector<'U>

Parameters

condition Func<T, Boolean>: A predicate that computes whether a value should be mapped.
function Func<T, U>: A delegate that represents a function of one variable

Type Parameters

U

Return Value

Vector<U>
The result of applying function to each element of this vector that matches condition. When condition is false, a missing value is returned.

Exceptions

ArgumentNullException

function is null.

-or-

condition is null.
