Constructor Details

WfsFeatureTable

public WfsFeatureTable(String url,
 String tableName)

Creates a WFS feature table with the given URL and table name.

Parameters:

url - the URL to the WFS service to connect to

tableName - the name of the layer (feature type) from the service

Throws:

IllegalArgumentException - if url or tableName are null or empty

Since:

100.5.0

WfsFeatureTable

public WfsFeatureTable(WfsLayerInfo wfsLayerInfo)

Creates a WFS feature table with the given WfsLayerInfo object.

Parameters:

wfsLayerInfo - a WfsLayerInfo object

Throws:

IllegalArgumentException - if wfsLayerInfo is null

Since:

100.5.0

Method Details

getFeatureRequestMode

public ServiceFeatureTable.FeatureRequestMode getFeatureRequestMode()

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

Currently, WFS feature table only supports ServiceFeatureTable.FeatureRequestMode.MANUAL_CACHE but defaults to ServiceFeatureTable.FeatureRequestMode.ON_INTERACTION_CACHE. Use setFeatureRequestMode(ServiceFeatureTable.FeatureRequestMode) to set the feature request mode to manual before attempting to populate the table.

Returns:

the feature request mode

Since:

100.5.0

setFeatureRequestMode

public void setFeatureRequestMode(ServiceFeatureTable.FeatureRequestMode featureRequestMode)

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

Currently, WFS feature 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 - the feature request mode

Throws:

IllegalArgumentException - if featureRequestMode is null

Since:

100.5.0

See Also:

• ServiceFeatureTable.FeatureRequestMode

getLayerInfo

public WfsLayerInfo getLayerInfo()

Gets the WFS layer metadata.

Returns:

a WfsLayerInfo object

Since:

100.5.0

getPreferredSpatialReference

public SpatialReference getPreferredSpatialReference()

Gets the preferred spatial reference of the WFS feature table.

Returns:

the preferred spatial reference of this WfsFeatureTable

Since:

100.5.0

setPreferredSpatialReference

public void setPreferredSpatialReference(SpatialReference spatialReference)

Sets the preferred spatial reference for the WFS feature table.

If the preferred spatial reference isn't available from the service, the table will fail to load. Specify a preferred spatial reference that matches the map or scene's spatial reference to avoid automatic reprojection. The preferred spatial reference cannot be changed on a loaded table.

Parameters:

spatialReference - the preferred spatial reference

Throws:

IllegalArgumentException - if spatialReference is null

Since:

100.5.0

See Also:

• SpatialReference

getAxisOrder

public OgcAxisOrder getAxisOrder()

Gets 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 populateFromServiceAsync(QueryParameters, boolean, Iterable). 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.

Returns:

the axis order type

Since:

100.5.0

setAxisOrder

public void setAxisOrder(OgcAxisOrder axisOrder)

Sets 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 populateFromServiceAsync(QueryParameters, boolean, Iterable). 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.

Parameters:

axisOrder - the axis order to use for this service

Throws:

IllegalArgumentException - if axisOrder is null

Since:

100.5.0

See Also:

• OgcAxisOrder

getFilterAxisOrder

public OgcAxisOrder getFilterAxisOrder()

Gets 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.NO_SWAP to send coordinates in (x,y) order. Defaults to OgcAxisOrder.AUTO.

Returns:

the axis order of the filter

Since:

100.5.0

setFilterAxisOrder

public void setFilterAxisOrder(OgcAxisOrder filterAxisOrder)

Sets 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.NO_SWAP to send coordinates in (x,y) order. Defaults to OgcAxisOrder.AUTO

Parameters:

filterAxisOrder - the filter axis order to use for this service

Throws:

IllegalArgumentException - if filterAxisOrder is null

Since:

100.5.0

See Also:

• OgcAxisOrder

getUri

public String getUri()

Gets the URL used to create the WFS feature table.

Specified by:

getUri in interface RemoteResource

Returns:

the service url of the WFS feature table

Since:

100.5.0

populateFromServiceAsync

public ListenableFuture<FeatureQueryResult> populateFromServiceAsync(QueryParameters query,
 boolean clearCache,
 Iterable<String> outFields)

Executes an asynchronous method that populates the table with the results of a query. The table must be in ServiceFeatureTable.FeatureRequestMode.MANUAL_CACHE mode.

WFS is only compatible with a subset of possible queries defined by QueryParameters. The 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.

Parameters:

query - the query to execute or default (empty) QueryParameters to get all features from the service

clearCache - true if this table should be cleared when this method is called, false if the result of the query should be appended to this table

outFields - the names of the fields to be populated or null/empty for the default set of fields

Returns:

a ListenableFuture that represents the result of the query; the results will replace or be appended to this table. The ListenableFuture indicates if the query isDone(); also allows cancellation. Calling get() on the returned future may throw an ExecutionException with its cause set to IOException if a network request fails.

Throws:

IllegalArgumentException - if query is null

Since:

100.5.0

populateFromServiceAsync

public ListenableFuture<FeatureQueryResult> populateFromServiceAsync(String xmlRequest,
 boolean clearCache)

Executes an asynchronous method that populates the table with the results of the XML query. The table must be in ServiceFeatureTable.FeatureRequestMode.MANUAL_CACHE mode.

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.

Parameters:

xmlRequest - an XML string representing the complete GetFeature request including but not limited to filters, joins, and aliases

clearCache - if true, clears existing table data before populating with the query result; if false, the result of the query should be appended to this table

Returns:

a ListenableFuture that represents the result of the query; the results will replace or be appended to this table. The ListenableFuture indicates if the query isDone(); also allows cancellation. Calling get() on the returned future may throw an ExecutionException with its cause set to IOException if a network request fails.

Throws:

IllegalArgumentException - if xmlRequest is null or empty

Since:

100.5.0
