An instance of this class represents the result of related queries. A prerequisite for querying related features is that all the participating tables must be part of a map, as either feature layers or non-spatial tables. An array of instances are returned, one per related table containing features related to the queried feature. This class has methods that can be used to iterate over the collection of related features.
Member Function Documentation
Esri::ArcGISRuntime::ArcGISFeature *RelatedFeatureQueryResult::feature() const
Returns the feature for which related features were queried.
[override virtual] QList<Esri::ArcGISRuntime::Field> RelatedFeatureQueryResult::fields() const
Reimplements: FeatureSet::fields() const.
Returns a list of Field objects representing the fields in this RelatedFeatureQueryResult.
[override virtual] Esri::ArcGISRuntime::GeometryType RelatedFeatureQueryResult::geometryType() const
Reimplements: FeatureSet::geometryType() const.
Returns the type of geometry shared by all features in this RelatedFeatureQueryResult.
This property is GeometryType::Unknown when the related table has no geometry field.
true if the result does not include all the features matched by the query.
Many ArcGIS services only return up to 1000 features even if the query matched more features. When that happens for the query that produces this result, this property is
[override virtual] Esri::ArcGISRuntime::FeatureIterator RelatedFeatureQueryResult::iterator() const
Reimplements: FeatureSet::iterator() const.
Returns an iterator used to iterate over all features in this RelatedFeatureQueryResult
Esri::ArcGISRuntime::ArcGISFeatureTable *RelatedFeatureQueryResult::relatedTable() const
Returns the related table for this query result.
There can be more than one instance of the same table or layer on the map with different scale level visibility, definition expression, and so on. All such instances share the same RelationshipInfo with the table the query operation is called on. In such cases, results from all such instances are returned, and
relatedTable is used to distinguish between them.
Esri::ArcGISRuntime::RelationshipInfo RelatedFeatureQueryResult::relationshipInfo() const
Returns the relationship info for this query result.
If more than one related table were queried, multiple results are returned, each with its RelationshipInfo.
[override virtual] Esri::ArcGISRuntime::SpatialReference RelatedFeatureQueryResult::spatialReference() const
Reimplements: FeatureSet::spatialReference() const.
Returns the spatial reference shared by all features in this RelatedFeatureQueryResult.
This property is set to an empty SpatialReference when the related table has no spatial reference.
