C1.LiveLinq.Hints.Indexed
Indexed Method
Indexed<T>(T, IndexingHintAction)
A hint with specified action.
Declaration
public static T Indexed<T>(this T value, IndexingHintAction action)Parameters
| Type | Name | Description |
|---|---|---|
| T | 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. |
| IndexingHintAction | action | The action specified by the hint. |
Returns
| Type | Description |
|---|---|
| T | Formally, the hint returns the same value that it receives in the parameter. In fact, it is never executed, its role is purely declarative. |
Type Parameters
| Name | Description |
|---|---|
| T | This can be any type, because hints are applicable to expressions of any type. |
Remarks
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.

Indexed<T>(T)
A hint with default action.
Declaration
public static T Indexed<T>(this T value)Parameters
| Type | Name | Description |
|---|---|---|
| T | 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. |
Returns
| Type | Description |
|---|---|
| T | Formally, the hint returns the same value that it receives in the parameter. In fact, it is never executed, its role is purely declarative. |
Type Parameters
| Name | Description |
|---|---|
| T | This can be any type, because hints are applicable to expressions of any type. |
Remarks
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.
