Indexed<T>(T) Method

Visual Basic
C#

'Declaration
 
Public Overloads Shared Function Indexed(Of T)( _
   ByVal value As T _
) As T

public static T Indexed<T>( 
   T value
)

Parameters

value: The value of the expression the hint is applied to. This value is not actually used by the hint, because the hint is never executed, its role is purely declarative.

Type Parameters

T: This can be any type, because hints are applicable to expressions of any type.

Return Value

Formally, the hint returns the same value that it receives in the parameter. In fact, it is never executed, its role is purely declarative.

Current default action is defined by the value of the static DefaultAction property. By default, it is IndexingHintAction.Optional.

Use the other Indexed overload if you need a hint with non-default action.

A hint does not change the value of the expression it is applied to. It only tells LiveLinq query optimizer to create and use an index on that expression, if possible. In fact, hints are removed from the expression before it is executed.
