FeatureTable class final

A table of features that typically represent real-world objects such as fire hydrants, roads, and forests.

This is the base class for a number of different feature tables, such as ServiceFeatureTable, FeatureCollectionTable, and GeoPackageFeatureTable.

The records in a feature table must all have geometry (shape and location) or have no geometry (just attribute values). If the records have geometry (FeatureTable.hasGeometry is true), you can display the features by creating a FeatureLayer from the feature table and adding the feature layer to the ArcGISMap or ArcGISScene's collection of operational layers (GeoModel.operationalLayers).

FeatureTable provides methods for spatial and attribute querying (for example, FeatureTable.queryFeatures), and methods to add, update, and delete features (such as FeatureTable.addFeature, FeatureTable.updateFeature, and FeatureTable.deleteFeature).
