MoreEnumerableFillBackwardT Method (IEnumerableT, FuncT, Boolean)

Returns a sequence with each missing element in the source replaced with the following non-missing element in that sequence. An additional parameter specifies a function used to determine if an element is considered missing or not.

Assembly: MoreLinq (in MoreLinq.dll) Version: 3.0.0

Syntax

C++

Copy

public static IEnumerable<T> FillBackward<T>(
	this IEnumerable<T> source,
	Func<T, bool> predicate
)

<ExtensionAttribute>
Public Shared Function FillBackward(Of T) ( 
	source As IEnumerable(Of T),
	predicate As Func(Of T, Boolean)
) As IEnumerable(Of T)

public:
[ExtensionAttribute]
generic<typename T>
static IEnumerable<T>^ FillBackward(
	IEnumerable<T>^ source, 
	Func<T, bool>^ predicate
)

[<ExtensionAttribute>]
static member FillBackward : 
        source : IEnumerable<'T> * 
        predicate : Func<'T, bool> -> IEnumerable<'T>

Parameters

source: Type: System.Collections.GenericIEnumerableT
The source sequence.
predicate: Type: SystemFuncT, Boolean
The function used to determine if an element in the sequence is considered missing.

Type Parameters

T: Type of the elements in the source sequence.

Return Value

Type: IEnumerableT
An IEnumerableT with missing values replaced.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

This method uses deferred execution semantics and streams its results. If elements are missing at the end of the sequence then they remain missing.
