public static Grouping<TInput> VariableWindow<TInput>(
	IList<TInput> index,
	Func<TInput, TInput, bool> condition,
	bool incremental,
	Direction direction
)

Public Shared Function VariableWindow(Of TInput) ( 
	index As IList(Of TInput),
	condition As Func(Of TInput, TInput, Boolean),
	incremental As Boolean,
	direction As Direction
) As Grouping(Of TInput)

public:
generic<typename TInput>
static Grouping<TInput>^ VariableWindow(
	IList<TInput>^ index, 
	Func<TInput, TInput, bool>^ condition, 
	bool incremental, 
	Direction direction
)

static member VariableWindow : 
        index : IList<'TInput> * 
        condition : Func<'TInput, 'TInput, bool> * 
        incremental : bool * 
        direction : Direction -> Grouping<'TInput> 

Parameters

index  IList<TInput>

The index the grouping is over.

condition  Func<TInput, TInput, Boolean>

A delegate that indicates whether two keys are in the same window.

incremental  Boolean

Indicates that the right edge of the window is not decreasing.

direction  Direction

Specifies whether the condition should be verified moving forward or backward through the values.

Type Parameters

TInput

The element type of the index.

Return Value

The extent of each window is determined by the first key value and condition. The window is extended as long as condition returns true whe applied to the first key and the subsequent keys.
