|
| GetACopy |
Copies this PFQuery using serialization.
|
| GetAggregationsFields |
Gets the names of all fields/columns used in aggregations.
|
| GetAllFilters |
Gets all filters in the filters tree, recursively.
|
| GetGroupsFields |
Gets the names of all fields/columns used in groups.
|

|
| GetSubGroupQuery(KeyValuePairString, Object) |
Creates a new PFQuery object retrieving values of a particular group.
The new query will replace one level of group by a filter on the same field. E.g. a gridview displaying groups will call this method to obtain the query to execute when one of the groups is opened. |

Adds a new sorting rule.
|
| OrderByDescending |
Starts to build a new query.
Adds a new sorting rule.
|
| Select |
Starts to build a new query.
Changes the way the query should determine which values are selected as output.
|
| Serialize |
Serializes this PFQuery in XML.
The returned string can be converted into a PFQuery using the static method PFQuery.CreateQuery(serializedQuery). |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Where(String, Object) |
Starts to build a new query.
Adds a new filter in the root node of filters tree.
|
