fun WfsFeatureTable(layerInfo: WfsLayerInfo)

Creates a new WFS feature table.

Functions

Link copied to clipboard
suspend fun addFeature(feature: Feature): Result<Unit>

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.

Link copied to clipboard
suspend fun addFeatures(features: Iterable<Feature>): Result<Unit>

Adds a collection of features to the table.

Link copied to clipboard
fun canAdd(): Boolean

Determines whether you can add a feature to a table.

Link copied to clipboard
open override fun cancelLoad()

Cancels loading metadata for the Loadable object.

Link copied to clipboard
fun canDelete(feature: Feature): Boolean

Determines whether you can delete a feature from a table.

Link copied to clipboard
fun canEditGeometry(): Boolean

Determines whether you can edit the geometry field in a table.

Link copied to clipboard
fun canUpdate(feature: Feature): Boolean

Determines whether you can update a feature in a table.

Link copied to clipboard
fun createFeature(): Feature

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.

fun createFeature(attributes: Map<String, Any?>, geometry: Geometry?): Feature

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.

suspend fun deleteFeature(feature: Feature): Result<Unit>

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.

suspend fun deleteFeatures(features: Iterable<Feature>): Result<Unit>

Deletes a collection of features from the table.

fun getField(fieldName: String): Field?

Retrieves the field with the given name.

Link copied to clipboard
open suspend override fun load(): Result<Unit>

Loads the metadata for the object.

Link copied to clipboard
suspend fun populateFromService(xmlRequest: String, clearCache: Boolean): Result<FeatureQueryResult>

Populate the table using an XML query. The XML query must be made against the same feature type represented by the WFS feature table. The schema of the query result must match or be a subset of the schema of the table.

suspend fun populateFromService(    parameters: QueryParameters?,     clearCache: Boolean,     outFields: Iterable<String>): Result<FeatureQueryResult>

Populate the table using 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. WFS is only compatible with a subset of possible queries defined by QueryParameters. Where clause only works when the table is backed by a service powered by GeoServer. Spatial queries (those that specify geometries) must use the Intersects spatial relationship.

suspend fun queryExtent(queryParameters: QueryParameters): Result<Geometry>

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.

Link copied to clipboard
suspend fun queryFeatureCount(queryParameters: QueryParameters): Result<Long>

Determines the count of features that satisfy the provided query parameters.

Link copied to clipboard
suspend fun queryFeatures(parameters: QueryParameters): Result<FeatureQueryResult>

Submits a query against the table.

Link copied to clipboard
suspend fun queryStatistics(statisticsQueryParameters: StatisticsQueryParameters): Result<StatisticsQueryResult>

Calculates values for the requested statistics. Statistics query parameters may also define fields on which results are grouped or sorted.

Link copied to clipboard
open suspend override fun retryLoad(): Result<Unit>

Loads or retries loading metadata for the object.

Link copied to clipboard
suspend fun updateFeature(feature: Feature): Result<Unit>

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.

Link copied to clipboard
suspend fun updateFeatures(features: Iterable<Feature>): Result<Unit>

Updates a collection of features in the table.

Properties

Link copied to clipboard
var axisOrder: OgcAxisOrder

The axis order, which defines how coordinates are interpreted. Some WFS services return coordinates in (X,Y) order, while others use (Y,X). Setting this property to OgcAxisOrder.Swap results in all coordinates in geometries being swapped from what was sent by the server. The axis order can be changed on a loaded table, but that change will only affect future calls to WfsFeatureTable.populateFromService(QueryParameters, Boolean, MutableListImpl). Features that are already in the table will not be modified. The default value is OgcAxisOrder.Auto. In this mode, the results are optimized using heuristics from popular WFS Servers.

Link copied to clipboard
var displayName: String

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().

val extent: Envelope?
Link copied to clipboard
var featureRequestMode: FeatureRequestMode

The mode defining when features are requested from the service. At v100.5, WFS feature table only supports FeatureRequestMode.ManualCache but defaults to FeatureRequestMode.OnInteractionCache. Set the feature request mode to manual before attempting to populate the table.

Link copied to clipboard
open val fields: List<Field>

The collection of Field objects representing the fields of the feature table.

Link copied to clipboard
var filterAxisOrder: OgcAxisOrder

The axis order of the filter, which determines how coordinates are ordered when sent to the server as part of spatial queries (those that specify a geometry). Some WFS services expect coordinates to be sent in (X,Y) order, while others use (Y,X). Use OgcAxisOrder.Swap to send coordinates in (Y,X) order. Use OgcAxisOrder.NoSwap to send coordinates in (X,Y) order. Defaults to OgcAxisOrder.Auto.

open val geometryType: GeometryType

The type of geometry of the features stored in this table. If FeatureTable.getHasGeometry() is false, then the geometry type is GeometryType.Unknown.

Link copied to clipboard
val hasGeometry: Boolean

True if the feature table supports geographic features, false otherwise.

Link copied to clipboard
val hasM: Boolean

True if the feature table supports geometries with M values, false otherwise.

Link copied to clipboard
val hasZ: Boolean

True if the feature table supports geometries with Z values, false otherwise.

Link copied to clipboard
val isEditable: Boolean

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.

Link copied to clipboard
open override var isPopupEnabled: Boolean

A flag indicating whether the PopupDefinition defined on the PopupSource is enable / disable. Will return false if an error occurs.

val layer: Layer?
Link copied to clipboard
val layerInfo: WfsLayerInfo?
Link copied to clipboard
open override val loadStatus: StateFlow<LoadStatus>

The load status.

Link copied to clipboard
val numberOfFeatures: Long

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.

Link copied to clipboard
open override var popupDefinition: PopupDefinition?

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.

var preferredSpatialReference: SpatialReference?
Link copied to clipboard
open val spatialReference: SpatialReference?
Link copied to clipboard
val tableName: String

The name of the table in the source dataset.

Link copied to clipboard
val url: String

The URL of the WFS feature table.
