    Detailed Description

    Corresponds to GPRecordSet and GPFeatureRecordSetLayer parameter types on the service.

    When Features are returned as an output parameter, the returned features are provided in a GeoprocessingFeatureSet. These features can be visualized on a map using a temporary Graphic on a GraphicsOverlay or using a FeatureCollectionTable on a FeatureCollectionLayer. If the geoprocessing service used is configured to use a result map server, then GeoprocessingResult::mapImageLayer is 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 of features or records, FeatureCollectionTable can be used.

    This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

    TypeDefault Property

    Note: A feature contains a geometry and some number of attributes. A record (or a row) is a feature that doesn't contain a geometry, only attributes.

    Property Documentation

    [read-only] canFetchOutputFeatures : bool

    Returns whether features can be fetched from the service of an output parameter (read-only).

    This property applies to output parameters. It indicates that the parameter is an output parameter that can fetch features from the geoprocessing service. Depending on the type of the service, the features may already be available.

    If features are not present then this property indicates that you can use fetchOutputFeatures to request features, asynchronously updating the features property.

    [default] features : FeatureSet

    The FeatureSet that is the source of the features.

    [read-only] fetchOutputFeaturesResult : FeatureSet

    Returns features from the fetchOutputFeatures task (read-only).

    [read-only] fetchOutputFeaturesStatus : Enums.TaskStatus

    Returns the current status of the fetchOutputFeatures method (read-only).

    See also Enums.TaskStatus.

    url : url

    The URL that is the source of the features.
