Public Shared Function VariableWindow(Of T) (

	incremental As Boolean,
	direction As Direction
) As Grouping(Of T)

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

static member VariableWindow : 
        index : Index<'T> * 
        condition : Func<'T, 'T, bool> * 
        incremental : bool * 
        direction : Direction -> Grouping<'T> 

Parameters

index

Type: Extreme.CollectionsIndexT
The index the grouping is over.

condition

Type: SystemFuncT, T, Boolean
A delegate that indicates whether two keys are in the same window.

incremental

Type: SystemBoolean
Indicates that the right edge of the window is not decreasing.

direction

Type: Extreme.CollectionsDirection
Specifies whether the condition should be verified moving forward or backward through the values.

Type Parameters

T

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 whe applied to the first key and the subsequent keys.
