public final class OgcFeatureCollectionTable
extends FeatureTable
implements RemoteResource

An OGC API - Features feature collection table.

To display data from an OGC feature collection table in a FeatureLayer use the FeatureLayer(FeatureTable) constructor where the OgcFeatureCollectionTable is the parameter that is passed into the constructor. Note: The OgcFeatureCollectionTable should not be confused with FeatureCollectionTable which is used as an input to create a FeatureCollectionLayer.

The ArcGIS Runtime API for OGC API Features provides building blocks for manipulating features on the Web. For more information about the OGC API Features specification see the documents: OGC API - Features - Part 1 and OGC API - Features - Part 2.

The class includes two important members: the getFeatureRequestMode() property and the populateFromServiceAsync(QueryParameters, boolean, List) method. Only the ServiceFeatureTable.FeatureRequestMode.MANUAL_CACHE mode is supported. This means OgcFeatureCollectionTable.populateFromServiceAsync(QueryParameters, boolean, List) must be called to populate, query, and return features from the service. For the QueryParameters.getWhereClause() that is used by the OgcFeatureCollectionTable.populateFromServiceAsync(QueryParameters, boolean, List) method, you can put any CQL2-TEXT or CQL2-JSON string as defined in the document OGC API - Features - Part3.

When populating or updating a local table from an OGC service, you can now request features in a specified SpatialReference (also referred to as SRS in ArcGIS or CRS in OGC). This leverages the power of the server to return features in the same spatial reference as your map rather than having to re-project them on the client.

This class supports loading and querying of features from a non-spatial OGC feature collection table.

Constructor Detail

OgcFeatureCollectionTable

public OgcFeatureCollectionTable(OgcFeatureCollectionInfo ogcFeatureCollectionInfo)

Constructs an OGCFeatureCollectionTable from the given OgcFeatureCollectionInfo.

Parameters:

ogcFeatureCollectionInfo - an OGCFeatureCollectionTable

Throws:

java.lang.IllegalArgumentException - if ogcFeatureCollectionInfo is null

Since:

100.9.0

OgcFeatureCollectionTable

public OgcFeatureCollectionTable(java.lang.String url,
                                 java.lang.String collectionId)

Constructs an OGCFeatureCollectionTable from the URL of the "OGC API - Features" service and the unique identifier for the collection.

Parameters:

url - the URL of the "OGC API - Features" service landing page that contains the feature collection

collectionId - the unique identifier for the collection from the service

Throws:

java.lang.IllegalArgumentException - if url is null or empty

java.lang.IllegalArgumentException - if collectionId is null or empty

Since:

100.9.0

Method Detail

setFeatureRequestMode

public void setFeatureRequestMode(ServiceFeatureTable.FeatureRequestMode featureRequestMode)

Sets the mode defining when features are requested from the service.

At v100.9, "OGC API - Features" collection table only supports ServiceFeatureTable.FeatureRequestMode.MANUAL_CACHE but defaults to ServiceFeatureTable.FeatureRequestMode.ON_INTERACTION_CACHE. Set the feature request mode to manual before attempting to populate the table.

Parameters:

featureRequestMode - a FeatureRequestMode

Throws:

java.lang.IllegalArgumentException - if featureRequestMode is null

Since:

100.9.0

getFeatureRequestMode

public ServiceFeatureTable.FeatureRequestMode getFeatureRequestMode()

Gets the mode defining when features are requested from the service.

At v100.9, "OGC API - Features" collection table only supports ServiceFeatureTable.FeatureRequestMode.MANUAL_CACHE but defaults to ServiceFeatureTable.FeatureRequestMode.ON_INTERACTION_CACHE. Set the feature request mode to manual before attempting to populate the table.

Returns:

a FeatureRequestMode

Since:

100.9.0

populateFromServiceAsync

public ListenableFuture<FeatureQueryResult> populateFromServiceAsync(QueryParameters queryParameters,
                                                                     boolean clearCache,
                                                                     java.util.List<java.lang.String> outfields)

Asynchronously populate the "OGC API - Features" feature collection table with the results of a query.

Use the default (empty) QueryParameters to get all features from the service. Specifying null or an empty List for outfields will result in the default set of outfields being used. Spatial queries (those that specify geometries) must use the QueryParameters.SpatialRelationship.INTERSECTS spatial relationship.

Parameters:

queryParameters - parameters that define how features are returned from the service

clearCache - set to true to clear existing table data before populating it with features returned from the service, false otherwise

outfields - an optional list of names of attribute fields to include in the output result, null or an empty list to include the default outfields set

Returns:

a ListenableFuture that represents the query operation on the service. When the query is done the result returns a list of FeatureQueryResult objects.

Throws:

java.lang.IllegalArgumentException - if queryParameters is null

Since:

100.9.0
