GeoPackageFeatureTable class final

A dataset in a GeoPackage containing features or non-spatial records.

A GeoPackageFeatureTable supports core GeoPackage geometry types and represents them as ArcGISPoint, Multipoint, Polyline, or Polygon. The GeoPackage specification supports a geometry collection type (storing a variety of core geometry types in a single table). For these tables, the first geometry type found in the collection is rendered.

You can query the dataset using attribute or spatial criteria, and if permitted, also edit the data. If the dataset contains geographic features you can display them on a map using a FeatureLayer.
