Detailed Description

A feature is a representation of a real-world object, such as a polygon to that represents a land parcel or a point that represents a location. All features have a fixed schema, which may contain:

  • A list model of attributes of the real-world entity it represents.
  • A geometry which describes the location and the shape of the entity.

Feature is the base class for a single feature from a FeatureTable. Classes that inherit from Feature have additional capabilities to support their specific uses.

Member Function Documentation

[signal] void Feature::geometryChanged()

Signal emitted when the geometry is changed.

This function was introduced in Esri::ArcGISRuntime 100.2.1.

See also GeoElement.

[override virtual] Feature::~Feature()

Destructor.

[override virtual] Esri::ArcGISRuntime::AttributeListModel *Feature::attributes() const

Reimplements: GeoElement::attributes() const.

Returns a list model of all the feature attributes as key-value pairs.

Esri::ArcGISRuntime::FeatureObjectType Feature::featureObjectType() const

Returns the type of feature.

Esri::ArcGISRuntime::FeatureTable *Feature::featureTable() const

Returns a reference to the FeatureTable that this feature came from.

[override virtual] Esri::ArcGISRuntime::Geometry Feature::geometry() const

Reimplements: GeoElement::geometry() const.

Returns the geometry for this feature.

See also setGeometry().

bool Feature::refresh()

Resets the attributes and geometry to the values in the data source, returning true on success or false otherwise.

Discards any in-memory changes to the Feature that have not been applied to the table, and reloads the Feature geometry and all attributes.

This function was introduced in Esri::ArcGISRuntime 100.4.

[override virtual] void Feature::setGeometry(const Esri::ArcGISRuntime::Geometry &geometry)

Reimplements: GeoElement::setGeometry(const Esri::ArcGISRuntime::Geometry &geometry).

Sets the geometry for the feature.

See also geometry().
