MoreEnumerableWindowedTSource Method

Processes a sequence into a series of subsequences representing a windowed subset of the original

Namespace: MoreLinq
Assembly: MoreLinq (in MoreLinq.dll) Version: 2.4.0

Syntax

public static IEnumerable<IEnumerable<TSource>> Windowed<TSource>(
	this IEnumerable<TSource> source,
	int size
)

<ExtensionAttribute>
Public Shared Function Windowed(Of TSource) ( 
	source As IEnumerable(Of TSource),
	size As Integer
) As IEnumerable(Of IEnumerable(Of TSource))

public:
[ExtensionAttribute]
generic<typename TSource>
static IEnumerable<IEnumerable<TSource>^>^ Windowed(
	IEnumerable<TSource>^ source, 
	int size
)

[<ExtensionAttribute>]
static member Windowed : 
        source : IEnumerable<'TSource> * 
        size : int -> IEnumerable<IEnumerable<'TSource>>

Parameters

source: Type: System.Collections.GenericIEnumerableTSource
The sequence to evaluate a sliding window over
size: Type: SystemInt32
The size (number of elements) in each window

Type Parameters

TSource: The type of the elements of the source sequence

Return Value

Type: IEnumerableIEnumerableTSource
A series of sequences representing each sliding window subsequence

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableTSource. 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

The number of sequences returned is: Max(0, sequence.Count() - windowSize) + 1
Returned subsequences are buffered, but the overall operation is streamed.
