Wfs Feature Table
A table of features that typically represents real-world objects from an OGC Web Feature Service (WFS) dataset. You can create WFS feature table using the URL of an OGC Web Feature Service and a specified layer name. Alternatively, you may connect to a com.arcgismaps.mapping.layers.WfsService, obtain its metadata from com.arcgismaps.mapping.layers.WfsService.serviceInfo, and discover its available layers using com.arcgismaps.mapping.layers.WfsServiceInfo.layerInfos. You can then create a WfsFeatureTable from an individual layer using WfsFeatureTable.WfsFeatureTable.
When you have created a WFS Feature table, features are not automatically requested. Instead, you must set the WFS Feature table request mode to FeatureRequestMode.ManualCache and then populate the table using WfsFeatureTable.populateFromService, for example.
You can visualize features from a WFS feature table using a com.arcgismaps.mapping.layers.FeatureLayer but the table does not support editing. See the OGC Web Feature Service standard for more information.

Properties
The axis order, which defines how coordinates are interpreted (x,y or y,x). Some WFS services return coordinates in (x,y) order, while others use (y,x) order. Setting this property to com.arcgismaps.mapping.layers.OgcAxisOrder.Swap results in all coordinates in geometries being swapped from what was sent by the server. Setting to com.arcgismaps.mapping.layers.OgcAxisOrder.NoSwap will cause coordinates to be interpreted as-is. The axis order can be changed on an already-loaded feature table, but the change will only affect future calls to WfsFeatureTable.populateFromService. Features that are already in the table will not be modified/swapped.
The mode defining when features are requested from the service. You must set the feature request mode to FeatureRequestMode.ManualCache before attempting to populate the table using WfsFeatureTable.populateFromService.
The filter axis order, which determines how coordinates are ordered when sent to the server as part of spatial queries. Some WFS services expect coordinates to be sent in (x,y) order, while others use (y,x). Use com.arcgismaps.mapping.layers.OgcAxisOrder.Swap to send coordinates in (y,x) order and OGCAxisOrder.noSwap to use (x,y) order.
Metadata describing the WFS layer, such as name and description.
The preferred spatial reference for the WFS feature table. If the service does not provide a preferred spatial reference, or you have not set it explicitly, then the table will fail to load. The preferred spatial reference cannot be changed once the table is loaded.
Inherited 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 com.arcgismaps.mapping.layers.FeatureLayer, the FeatureTable.displayName is used as the com.arcgismaps.mapping.layers.FeatureLayer.name.
The type of geometry of the features stored in this table. If FeatureTable.hasGeometry is false, then the geometry type is com.arcgismaps.geometry.GeometryType.Unknown.
True if the feature table supports geographic features, false otherwise.
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 layer that displays this table, if any. The com.arcgismaps.mapping.layers.Layer type depends on how the feature table is created. For example, a com.arcgismaps.mapping.layers.Layer will be an com.arcgismaps.mapping.layers.AnnotationLayer if the FeatureTable is created from a table that supports annotation. See com.arcgismaps.mapping.layers.Layer for more information about the supported layer types.
The load status.
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.numberOfFeatures will return the full number of features.
The pop-up definition. The PopupDefinition associated with the popup source. A null if an error occurs or if the popup source is not associated with a pop-up definition.
The spatial reference of the table. A spatial reference defines how the coordinates of a feature's com.arcgismaps.geometry.Geometry correspond to locations in the real world. For more information, see the com.arcgismaps.geometry.SpatialReference class or the Spatial references documentation.
Functions
Populates the table using an XML query. The schema of the query result must match or be a subset of the schema of the table. The XML query must be made against the same feature type represented by the WFS feature table.
Populates the WFS feature table using the query parameters. Use the default (empty) QueryParameters to get all features from the service. If you specify a null or an empty collection for outfields, then the default set of outfields are used.
Inherited functions
Adds a feature to the table. Adding a feature that contains a com.arcgismaps.geometry.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 com.arcgismaps.geometry.SpatialReference.
Adds a collection of features to the table.
Determines whether you can add new features to the table. Although this method may state that the table allows new features to be added, the application may not be licensed to permit this. For example, a user cannot add features to a secured feature table if the application is licensed at the Lite level (com.arcgismaps.LicenseLevel.Lite).
Cancels loading metadata for the Loadable object.
Determines whether you can delete the feature from the table. Although this method may state that the table allows the feature to be deleted, the application may not be licensed to permit this. For example, a user cannot delete features from a secured feature table if the application is licensed at the Lite level (com.arcgismaps.LicenseLevel.Lite).
Determines whether you can edit the geometry field in a table. Although this method may state that the table allows geometry fields to be edited, the application may not be licensed to permit this. For example, a user cannot update geometry in a secured feature table if the application is licensed at the Lite level (com.arcgismaps.LicenseLevel.Lite).
Determines whether you can update the feature in the table. Although this method may state that the table allows the feature to be updated, the application may not be licensed to permit this. For example, a user cannot update features in a secured feature table if the application is licensed at the Lite level (com.arcgismaps.LicenseLevel.Lite).
Creates a new empty feature. The new feature is only available in memory at this point. Execute FeatureTable.addFeature 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 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 to determine if this operation is allowed.
Deletes a collection of features from the table.
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 com.arcgismaps.geometry.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 com.arcgismaps.geometry.SpatialReference.
Updates a collection of features in the table.
