Class GeoprocessingFeatures

java.lang.Object

com.esri.arcgisruntime.tasks.geoprocessing.GeoprocessingParameter

com.esri.arcgisruntime.tasks.geoprocessing.GeoprocessingFeatures

All Implemented Interfaces:

RemoteResource

public final class GeoprocessingFeatures
extends GeoprocessingParameter
implements RemoteResource

Corresponds to GPRecordSet and GPFeatureRecordSetLayer parameter types in the service REST specification.

A geoprocessing features has a getFeatures() method that returns a FeatureSet. You can call GeoElement.getAttributes() on these Features to get the attributes. Note that these features are not held in a FeatureTable.

When geoprocessing features are returned as an output parameter the returned results are provided as a GeoprocessingFeatureSet. These features can be visualized on a map using temporary Graphic in a GraphicsOverlay or using a FeatureCollectionTable in a FeatureLayer. If the geoprocessing service is configured to use a result map server, then GeoprocessingResult.getMapImageLayer() can be used to visualize the results using the symbology predefined by the service.

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

Constructor Detail

GeoprocessingFeatures

public GeoprocessingFeatures()

Creates an instance.

Since:

100.0.0

GeoprocessingFeatures

public GeoprocessingFeatures(FeatureSet featureSet)

Creates an instance containing features.

Parameters:

featureSet - the set of features

Throws:

IllegalArgumentException - if featureSet is null

Since:

100.0.0

GeoprocessingFeatures

public GeoprocessingFeatures(String url)

Creates an instance based on a URL to features.

Parameters:

url - the URL

Throws:

IllegalArgumentException - if the URL is null or empty

Since:

100.0.0

Method Detail

getUrl

public String getUrl()

Returns the URL or empty string if this has not been set.

Returns:

the URL

Since:

100.0.0

setUrl

public void setUrl(String url)

Sets the URL. If a URL is set then any features set with setFeatures(FeatureSet) will be ignored.

Parameters:

url - the URL

Throws:

IllegalArgumentException - if url is null or empty

Since:

100.0.0

getFeatures

public FeatureSet getFeatures()

The feature set. If null is returned then check if canFetchOutputFeatures() is true and if it is use fetchOutputFeaturesAsync() to populate the result.

Returns:

the result features

Since:

100.0.0

setFeatures

public void setFeatures(FeatureSet features)

Sets the features. This should only be set when using this instance as an input parameter. This property will be ignored if setUrl(String) is set.

Parameters:

features - the features to use

Throws:

IllegalArgumentException - if features is null

Since:

100.0.0

canFetchOutputFeatures

public boolean canFetchOutputFeatures()

Indicates if features can be fetched from the service for an output parameter.

Returns:

true, if features can be fetched

Since:

100.0.0

fetchOutputFeaturesAsync

public ListenableFuture<Void> fetchOutputFeaturesAsync()

Asynchronously requests features from the service. It is not necessary to call this if getFeatures() is already populated. Add a done listener to the listenable future to know when this method has completed. Once the future has completed, calling getFeatures() will return the features.

Returns:

a listenable future that will be done when the features have been fetched

Since:

100.0.0

Specified by:

getCredential in interface RemoteResource

Returns:

the credential used for authentication

Since:

setCredential

public void setCredential(Credential credential)

Sets the credential used to authenticate the user with the geoprocessing service.

Specified by:

setCredential in interface RemoteResource

Parameters:

credential - the credential used for authentication

Since:

getRequestConfiguration

public RequestConfiguration getRequestConfiguration()

Gets the RequestConfiguration object that contains parameters used for sending a network request using this parameter object - See fetchOutputFeaturesAsync().

Specified by:

getRequestConfiguration in interface RemoteResource

Returns:

the RequestConfiguration object or default values if nothing was set

Since:

100.0.0

See Also:

Specified by:

setRequestConfiguration in interface RemoteResource

Parameters:

requestConfiguration - contains the parameters to use
