ArcGISFeature

A Feature stored in an ArcGISFeatureTable. An ArcGISFeature can contain:

• A set of attributes that describe the real-world entity it represents

• A geometry that defines its location and shape. The geometry might contain m-values, which are typically used for linear referencing.

• Zero or more feature attachments such as images or documents

A feature's attribute values can be changed, but attribute definitions cannot be added, deleted, or modified.

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 ArcGISFeatures in a minimum state will return 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 Loadable.load() on each feature

• Call ServiceFeatureTable.loadOrRefreshFeatures(MutableListImpl) and pass a mutable array of the features to be loaded

• Call ServiceFeatureTable.queryFeatures(QueryParameters, QueryFeatureFields) with the constant QueryFeatureFields.LoadAll, which returns all features in a fully loaded state

For more information, see the class description for ServiceFeatureTable.
