GeoprocessingFeatures class final

The geoprocessing features used as input or output parameters.

Corresponds to GPRecordSet and GPFeatureRecordSetLayer parameter types on the service.

A feature contains a GeoprocessingFeatures.features and may contains extra attributes on GeoElement.attributes collection. A record (or a row) doesn't contain Feature and information is stored in attributes on GeoElement.attributes collection.

When GeoprocessingFeatures.features are returned as an output parameter the returned results are provided as a read-only list of Feature using GeoprocessingFeatureSet. These features can be visualized on a map using temporary Graphic on a GraphicsOverlay or using FeatureCollectionTable on a FeatureCollectionLayer. If used geoprocessing service is configured to use a result map server, then GeoprocessingResult.mapImageLayer was populated and it can be used to visualize the results using the symbology predefined by the service.

When providing GeoprocessingFeatures as an input to the geoprocessing task, features can be provided directly from the FeatureQueryResult that was returned from the FeatureTable. If there is a need to create a new set a features or records, FeatureCollectionTable can be used.
