Methods
| Name | Description | |
|---|---|---|
| ApplyParametersTo |
Applies this where condition to the target object
(Inherited from QueryParametersBase TParent .) |
| As |
Sets the alias to the column
(Inherited from SelectQueryColumnBase ParentType .) |
| AsAlias |
Returns the new column created from this column alias
(Inherited from QueryColumnBase ParentType .) |
| AsValue |
Gets a query expression representing this object as a value
(Inherited from QueryColumnBase ParentType .) |
| CallOnDispose |
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 .) |
| CloneObject |
Creates the clone of the object.
(Inherited from QueryParametersBase TParent .) |
| CopyPropertiesTo |
Copies all the object properties to the given target class
(Inherited from QueryParametersBase TParent .) |
| 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.) |
 | FromExpression |
Creates a query column from the given expression
|
| GetExpression |
Gets the expression for the column data
(Inherited from SelectQueryColumnBase ParentType .) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the (Inherited from Type of the current instance.Object.) |
| GetValueExpression |
Gets the value expression of the columns
(Overrides SelectQueryColumnBase ParentType GetValueExpression .) |
| Changed |
Marks the object as changed
(Inherited from AbstractQueryObject.) |
| Immutable |
Makes this object instance is immutable, and next subsequent modification starts with a clone of the object.
(Inherited from QueryParametersBase TParent .) |
| IncludeDataParameters |
Adds the data parameters to the current query parameters
(Inherited from QueryParametersBase TParent .) |
| Lock |
Locks the event on the given lock object. The context stays locked until the handler is disposed.
(Inherited from DisposableObject.) |
| MemberwiseClone | Creates a shallow copy of the current (Inherited from Object.Object.) |
| NewResult |
Returns properly typed this
(Inherited from QueryParametersBase TParent .) |
| Snapshot |
Creates an immutable snapshot of the current query as a base for further evaluation. Doesn't modify the original query in any way.
(Inherited from QueryParametersBase TParent .) |
| ToString |
Returns the string representation of the expression
(Inherited from QueryParametersBase TParent .) |
| ToString(Boolean) |
Returns the string representation of the expression, with possibility of expanding parameters
(Inherited from QueryColumnBase ParentType .) |
| Using |
Adds the given object to the list of the allocated objects to dispose
(Inherited from DisposableObject.) |
