Ogc
An OGC API - Features feature collection table. To display data from an OGC feature collection table in a FeatureLayer use the FeatureLayer.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.
This API provides building blocks for manipulating OGC Features on the Web. For more information about the OGC API Features specification see the documents: OGC API - Features - Part 1[https://docs.opengeospatial.org/is/17-069r3/17-069r3.html] and https://docs.opengeospatial.org/is/18-058/18-058.html.
The class includes two important members: the OgcFeatureCollectionTable.getFeatureRequestMode() property and the OgcFeatureCollectionTable.populateFromService(QueryParameters, Boolean, MutableListImpl) method. Only the FeatureRequestMode.ManualCache mode is supported. This means OgcFeatureCollectionTable.populateFromService(QueryParameters, Boolean, MutableListImpl) must be called to populate, query, and return features from the service. For the QueryParameters.getWhereClause() that is used by the OgcFeatureCollectionTable.populateFromService(QueryParameters, Boolean, MutableListImpl) method, you can put any CQL2-TEXT or CQL2-JSON string as defined in the document https://docs.ogc.org/DRAFTS/21-065.html.
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.
Constructors
Creates a new OGC API - Features feature collection table
Creates a new OGC API - Features feature collection table.
Functions
Adds a feature to the table. Adding a feature that contains a Geometry causes the geometry to become simplified. This may change a single part geometry to a multipart geometry, or round off X, Y, Z, and M coordinate values that are above the resolution set by the SpatialReference.
Adds a collection of features to the table.
Cancels loading metadata for the Loadable object.
Determines whether you can edit the geometry field in a table.
Creates a new empty feature. The new feature is only available in memory at this point. Execute FeatureTable.addFeature(Feature) to commit the new Feature to the table.
Creates a new feature with the provided attribute values and, optionally, geometry. The new feature is only available in memory at this point. Execute FeatureTable.addFeature(Feature) to commit the new Feature to the table.
Deletes a feature from the table. Deleting a feature from a GeodatabaseFeatureTable in a stand-alone mobile geodatabase created with ArcGIS Pro is not supported when the table participates in a controller dataset, such as a utility network or parcel fabric. Use FeatureTable.canDelete(Feature) to determine if this operation is allowed.
Deletes a collection of features from the table.
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 MutableListImpl for outfields will result in the default set of outfields being used. Spatial queries (those that specify geometries) must use the Intersects spatial relationship.
Determines the minimum bounding envelope that contains features satisfying the provided query parameters. If no features meet the query criteria, an empty envelope is returned.
Determines the count of features that satisfy the provided query parameters.
Submits a query against the table.
Calculates values for the requested statistics. Statistics query parameters may also define fields on which results are grouped or sorted.
Updates a feature in the table. If you update a feature that contains a Geometry, the geometry becomes simplified. This may change a single part geometry to a multipart geometry, or round X, Y, Z, and M coordinate values that are above the resolution set by the SpatialReference.
Updates a collection of features in the table.
Properties
A user-friendly name that can be displayed in the UI (for example, in a Table of Contents). If the table is displayed with a FeatureLayer, the FeatureTable.getDisplayName() is used as the FeatureLayer.getName().
The mode defining when features are requested from the service. Warning: At v100.9, OGC API - Features collection table only supports FeatureRequestMode.ManualCache but defaults to FeatureRequestMode.OnInteractionCache. Set the feature request mode to manual before attempting to populate the table.
The type of geometry of the features stored in this table. If FeatureTable.getHasGeometry() is false, then the geometry type is GeometryType.Unknown.
True if this feature table is editable, false otherwise. Underlying file permissions (for subclasses such as ShapefileFeatureTable and GeodatabaseFeatureTable) can be changed while the feature table is open. In these cases the value of this property may not be accurate.
A flag indicating whether the PopupDefinition defined on the PopupSource is enable / disable. Will return false if an error occurs.
The number of features in the table. If all the features are stored in the local table, for example with a GeodatabaseFeatureTable or a ShapefileFeatureTable, then the FeatureTable.getNumberOfFeatures() will return the full number of features.
