Class Overview
A collection of features returned from ArcGIS Server or used as input to tasks. Each feature in the FeatureSet may contain geometry, attributes, symbology, and an InfoTemplate. If the FeatureSet does not contain geometry, and only contains attributes, the FeatureSet can be treated as a table where each feature is a row object. Tasks that return FeatureSet include QueryTask and GeoProcessor. In addition, GeoProcessor may require FeatureSet as input.
