Class ArcGISFeature
Represents an ArcGIS specific feature stored in an ArcGISFeatureTable.
Namespace: Esri.ArcGISRuntime.Data
Assembly: Esri.ArcGISRuntime.dll
Syntax
public sealed class ArcGISFeature : Feature, INotifyPropertyChanged, ILoadableRemarks
ArcGIS features are stored in ArcGIS specific data sources such as a GeodatabaseFeatureTable or ServiceFeatureTable. Since ArcGISFeature is a subclass of Feature, it contains a geometry that defines its location and shape, and a set of attributes that describe the real-world entity it represents.
In addition, ArcGISFeature objects can also contain:
- Feature attachments such as images or documents, that can be edited, updated or deleted.
- Feature subtypes that define different default values or domains for fields.
- The ability to relate this feature to another ArcGISFeature.
- Geometry that has m-values, which are typically used for linear referencing.
If you create a ServiceFeatureTable from the URL of a feature service, features in the table are initially in one of the following states:
- A minimum set of attributes are available in the table, and m-values are omitted. This is an optimization for faster rendering.
- All attributes defined by the service are available in the table, including m-values, which might be NaN.
The initial state of features is determined by the feature request mode of the table. For important details, see FeatureRequestMode.
By default, a query on ArcGISFeature objects in a minimum state returns them in the same state. To access all attributes (or the m-values) of features returned by a query, you must load the features. You can do one of the following:
- Call LoadAsync() on each feature.
- Call LoadOrRefreshFeaturesAsync(IEnumerable<Feature>) and pass a collection of features to be loaded.
- Call QueryFeaturesAsync(QueryParameters, QueryFeatureFields) with the constant LoadAll, which returns all features in a fully loaded state.
For more information, see the class description for ServiceFeatureTable.
