Description
Parameters to perform a statistic query using AGSFeatureTable.
Instances of this class represent parameters that can be used to perform a statistic query using queryStatisticsWithParameters:completion: (AGSFeatureTable).
All parameters related to geometry and spatial queries will be ignored when querying non spatial data.

Method Documentation
◆ initWithStatisticDefinitions:
| - (instancetype) initWithStatisticDefinitions: | (NSArray< AGSStatisticDefinition * > *) | statisticDefinitions |
Intialize the query parameter with the provided statistic definitions
- Parameters
-
statisticDefinitions describing which statistics are required in the query result
- Returns
- An initialized query parameter
- Since
- 100.2
◆ statisticsQueryParametersWithStatisticDefinitions:
| + (instancetype) statisticsQueryParametersWithStatisticDefinitions: | (NSArray< AGSStatisticDefinition * > *) | statisticDefinitions |
Intialize the query parameter with the provided statistic definitions
- Parameters
-
statisticDefinitions describing which statistics are required in the query result
- Returns
- An initialized query parameter
- Since
- 100.2
Property Documentation
◆ geometry
|
readwritenonatomicstrong |
The geometry to use while performing a spatial query. Valid geometry types are AGSEnvelope, AGSPoint, AGSMultipoint, AGSPolygon, and AGSPolyline. Results of the query will include only those features which conform to the specified spatialRelationship with this geometry.
- Since
- 100.2
◆ groupByFieldNames
|
readwritenonatomiccopy |
The fields by which statistical query results should be grouped.
- Since
- 100.2
◆ orderByFields
|
readwritenonatomiccopy |
Fields by which the results need to be ordered. Note, the service being queried must support advanced queries.
- Since
- 100.2
◆ spatialRelationship
|
readwritenonatomicassign |
The spatial constraint that needs to be applied on the query geometry. Only data satisfying this relationship will be returned as results.
- Since
- 100.2
◆ statisticDefinitions
|
readwritenonatomiccopy |
The definition of which statistics (input field, output name, statistic type) to include in the results of statistical query.
- Since
- 100.2
◆ timeExtent
|
readwritenonatomicstrong |
Time extent for the query. Only features that fall within this time period will be returned.
- Since
- 100.2
◆ whereClause
|
readwritenonatomiccopy |
A SQL where clause to filter results for the query. If the where clause includes dates, they must be correctly formatted based on the geodatabase datasource used in the service. Refer to this document for date formats expected by different datasources.
