MoreEnumerableFillBackwardT Method (IEnumerableT, FuncT, Boolean, FuncT, T, T)

Returns a sequence with each missing element in the source replaced with the following non-missing element in that sequence. Additional parameters specifiy two functions, one used to determine if an element is considered missing or not and another to provide the replacement for the missing element.

Namespace:  MoreLinq
Assembly:  MoreLinq (in MoreLinq.dll) Version: 2.4.0
public static IEnumerable<T> FillBackward<T>(
	this IEnumerable<T> source,
	Func<T, bool> predicate,
	Func<T, T, T> fillSelector


Type: System.Collections.GenericIEnumerableT
The source sequence.
Type: SystemFuncT, Boolean
The function used to determine if an element in the sequence is considered missing.
Type: SystemFuncT, T, T
The function used to produce the element that will replace the missing one. It receives the next non-missing element as well as the current element considered missing.

Type Parameters

Type of the elements in the source sequence.

Return Value

Type: IEnumerableT
An IEnumerableT with missing elements filled.

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