Methods
| Name | Description | |
|---|---|---|
| AddWhereCondition |
Adds the given where condition to the final where condition
|
| AddWhereConditionInternal |
Adds the given where condition

|
| And(IWhereCondition) |
Adds the given where condition with the AND operator
|

Adds the given where condition with the AND operator. Creates a new where condition object and runs the setup actions on it.
|
| AnySettingsDefined |
Returns true if the object has any settings defined that influence the resulting query
|
| ApplyParametersTo |
Applies this where condition to the target object
(Overrides QueryParametersBase TParent ApplyParametersTo(IQueryObject).) |

Adds the given action to the list of actions called when the handler object is disposed
(Inherited from DisposableObject.) |
| Clone |
Creates the clone of the object.
(Inherited from QueryParametersBase TParent .) |

Creates the clone of the object.
(Inherited from QueryParametersBase TParent .) |
| CopyPropertiesTo |
Creates the clone of the collection.
(Overrides QueryParametersBase TParent CopyPropertiesTo(IQueryObject).) |
| Dispose |
Make sure the objects get disposed
(Inherited from DisposableObject.) |
| EnsureParameters |
Ensures data parameters for the given query
(Inherited from QueryParametersBase TParent .) |
|  Equals | (Inherited from Object.) |
| Expand |
Expands the expression by replacing parameters with their values
(Inherited from QueryParametersBase TParent .) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |

|
| Changed |
Marks the object as changed
(Inherited from AbstractQueryObject.) |
| CheckReturnsNoResults |

(Inherited from QueryParametersBase TParent .) |
