Detailed Description
Operations that query, select and populate features, such as FeatureTable::queryFeaturesAsync(const Esri::ArcGISRuntime::QueryParameters&, QObject*), FeatureLayer::selectFeaturesAsync(const Esri::ArcGISRuntime::QueryParameters&, Esri::ArcGISRuntime::SelectionMode, QObject*), AnnotationLayer::selectedFeaturesAsync, or ServiceFeatureTable::populateFromServiceAsync(const Esri::ArcGISRuntime::QueryParameters&, bool, const QStringList&, QObject*), return their resulting features in a collection of FeatureQueryResult objects.
Each FeatureQueryResult provides a GeometryType, SpatialReference, and a collection of Field objects for each resulting feature.
Relevant samples:
- Feature collection layer (query): Create a feature collection layer to show a query result from a service feature table.
- Feature layer query: Find features in a feature table which match an SQL query.
- List related features: List features related to a selected feature.
- Query map image sublayer: Find features in a sublayer based on attributes and location.
Member Function Documentation
[override virtual] FeatureQueryResult::~FeatureQueryResult ()
Destructor
[override virtual] QList<Esri::ArcGISRuntime::Field > FeatureQueryResult::fields() const
Reimplements: FeatureSet::fields() const.
Returns a list of Field objects representing the fields in this FeatureQueryResult.
[override virtual] Esri::ArcGISRuntime::GeometryType FeatureQueryResult::geometryType () const
Reimplements: FeatureSet::geometryType() const.
Returns the type of geometry shared by all features in this FeatureQueryResult.
bool FeatureQueryResult::isTransferLimitExceeded () const
Returns true if the query resulted in a larger number of features than what the transfer limit supports, false otherwise.
Many ArcGIS services only return up to 1000 results even if the query matched more features. When that happened for the query that produced these results, this property is true.
[override virtual] Esri::ArcGISRuntime::FeatureIterator FeatureQueryResult::iterator() const
Reimplements: FeatureSet::iterator() const.
Returns an iterator used to iterate over all features in this FeatureQueryResult
[override virtual] Esri::ArcGISRuntime::SpatialReference FeatureQueryResult::spatialReference () const
Reimplements: FeatureSet::spatialReference() const.
Returns the spatial reference shared by all features in this FeatureQueryResult.
