Specification

WFSStrategy

AbstractWFSStrategy

StrictWFS_1_x_Strategy

CubeWerxStrategy

public class CubeWerxStrategy
extends StrictWFS_1_x_Strategy

A strategy object to aid in querying a CubeWerx WFS 1.1 server

This strategy was created as per the limitations encountered at the CubeWerx server being tested while developing this plugin.

For instance, the following issues were found:

• resultType parameter is not supported in GetFeature
• Logically grouped spatial filters can't be handled
• CubeWerx does not support logical filters containing mixed geometry filters (eg, AND(BBOX, Intersects)), no matter what the capabilities doc says

Method Detail

supports

public boolean supports(GetFeatureRequest.ResultType resultType)

Overrides:

supports in class StrictWFS_1_x_Strategy

Returns:

true only if resultType == results, CubeWerx throws a service exception if the resultType parameter is set on a POST request, no matter it's value, and on a GET request it's just ignored; also the returned feature collection does not contain the number of features matched.

buildGetFeatureParametersForGET

protected Map<String,String> buildGetFeatureParametersForGET(GetFeatureRequest request)

Removes the RESULTTYPE.

Overrides:

buildGetFeatureParametersForGET in class AbstractWFSStrategy

AbstractWFSStrategy.buildGetFeatureParametersForGET(org.geotools.data.wfs.internal.GetFeatureRequest)

getPostContents

public InputStream getPostContents(WFSRequest request)
                            throws IOException

Description copied from class: AbstractWFSStrategy

Returns the input stream with the POST body contents for the given request.

Overrides:

getPostContents in class AbstractWFSStrategy

Throws:

IOException

AbstractWFSStrategy.createDescribeFeatureTypeRequestPost(org.geotools.data.wfs.internal.DescribeFeatureTypeRequest), AbstractWFSStrategy.createGetFeatureRequestPost(org.geotools.data.wfs.internal.GetFeatureRequest), AbstractWFSStrategy.prepareEncoder(org.geotools.data.wfs.internal.WFSRequest), AbstractWFSStrategy.getOperationName(org.geotools.data.wfs.internal.WFSOperationType)

splitFilters

public Filter[] splitFilters(QName typeName,
                             Filter queryFilter)

Description copied from class: AbstractWFSStrategy

Splits the filter provided by the geotools query into the server supported and unsupported ones.

Overrides:

splitFilters in class AbstractWFSStrategy

Returns:

a two-element array where the first element is the supported filter and the second the one to post-process
