IdentifyLayerResult Class | ArcGIS Maps SDK for Qt

IdentifyLayerResult

class Esri::ArcGISRuntime::IdentifyLayerResult

The identify layer result contains the identified geoelements of a layer. More...

List of all members, including inherited members

Public Functions Detailed Description

Operations that identify the geoelements in a layer, such as GeoView::identifyLayerAsync(Esri::ArcGISRuntime::Layer*, const QPointF&, double, bool, QObject*) or GeoView::identifyLayersAsync(const QPointF&, double, bool, QObject*), return the resulting geoelements in a geoElements collection for each layer.

Obtain these results through the identifyLayersCompleted signal.

Relevant samples:

Configure clusters: Add client side feature reduction on a point feature layer that is not pre-configured with clustering.
Display clusters: Display a web map with a point feature layer that has feature reduction enabled to aggregate points into clusters.
Identify KML features: Show a callout with formatted content for a KML feature.
Identify layers: Identify features in all layers in a map.
Identify raster cell: Get the cell value of a local raster at the tapped location and display the result in a callout.
Scene layer selection: Identify features in a scene to select.
Show popup: Show predefined popups from a web map.

Member Function Documentation [override virtual noexcept] IdentifyLayerResult::~IdentifyLayerResult()

Destructor.

Esri::ArcGISRuntime::Error IdentifyLayerResult::error() const

Returns the error that occurred during the identify operation, if there is one.

QList<Esri::ArcGISRuntime::GeoElement *> IdentifyLayerResult::geoElements() const

Returns the collection of identified geoelements.

If there are no geoelement results at the layer level (for layers where geoelement results are exposed in sublayer results), an empty QList is returned. The function will always return an QList containing objects that implement GeoElement. The specific type of geoelement in the collection depends on the type of objects contained in the layer and whether AggregationFeatureReduction is enabled on the layer. When AggregationFeatureReduction is enabled on the layer, geoelements in the QList will be either AggregateGeoElement or the GeoElement type contained in the layer.

bool IdentifyLayerResult::isTransferLimitExceeded() const

Returns true if the transfer limit was exceeded for the identify results, false otherwise.

Esri::ArcGISRuntime::LayerContent *IdentifyLayerResult::layerContent() const

Returns the layer that contains the identified geoelements.

The element will contain an object that implements LayerContent. This may be either an ArcGISSublayer or a Layer.

QList<Esri::ArcGISRuntime::Popup *> IdentifyLayerResult::popups() const

Returns a QList of identified popups.

The list of popups may be empty if the layer is composed of sub layers, in which case sublayerResults will be populated with results from sub layers.

Only valid when the identify was called with the returnPopupsOnly parameter set to true.

QList<Esri::ArcGISRuntime::IdentifyLayerResult *> IdentifyLayerResult::sublayerResults() const

Returns the identify layer result's QList of sub results.

For layers that do not contain sublayers, the QList will be empty.
