org.opengis.cite.iso19142.basic.filter.spatial.IntersectsTests

public class IntersectsTests
extends QueryFilterFixture

Tests the response to a GetFeature request that includes the spatial predicate Intersects. This predicate is the logical complement of the Disjoint predicate; that is:

 a.Intersects(b) ⇔ ! a.Disjoint(b)

Method Detail

implementsSpatialFilter

public void implementsSpatialFilter(org.testng.ITestContext testContext)

Checks the value of the filter constraint "ImplementsSpatialFilter" in the capabilities document. All tests are skipped if this is not "TRUE".

Parameters:

testContext - Information about the test run environment.

findAllGeometryProperties

public void findAllGeometryProperties()

Finds the geometry properties for all feature types recognized by the SUT.

implementsIntersectsOp

public void implementsIntersectsOp()

Checks if the spatial operator "Intersects" is implemented and which geometry operands are supported. If it's not implemented, all tests for this operator are skipped.

intersectsPolygon

public void intersectsPolygon(ProtocolBinding binding,
                              QName featureType)
                       throws XPathExpressionException

[Test] Submits a GetFeature request containing an Intersects predicate with a gml:Polygon operand. The response entity must be schema-valid and contain only matching instances.

Parameters:

binding - The ProtocolBinding to use for this request.

featureType - A QName representing the qualified name of some feature type.

Throws:

XPathExpressionException

intersectsCurve

public void intersectsCurve(ProtocolBinding binding,
                            QName featureType)
                     throws XPathExpressionException

[Test] Submits a GetFeature request containing an Intersects predicate with a gml:LineString or gml:Curve (LineStringSegment) operand. The response entity must be schema-valid and contain only matching instances.

Parameters:

binding - The ProtocolBinding to use for this request.

featureType - A QName representing the qualified name of some feature type.

Throws:

XPathExpressionException

buildGetFeatureRequest

Document buildGetFeatureRequest(QName featureType,
                                String operator,
                                org.apache.xerces.xs.XSElementDeclaration propertyDecl,
                                Element literal)

Builds a simple GetFeature request entity that contains a basic filter expression.

Parameters:

featureType - The name of the feature type.

operator - The name of the filter predicate (operator).

propertyDecl - The declaration of the feature property to be queried.

literal - An element representing the literal value to match.

Returns:

A Document containing a request entity with wfs:GetFeature as the document element.

addSpatialPredicate

void addSpatialPredicate(Document request,
                         String spatialOp,
                         Element gmlGeom,
                         Element valueRef)

Adds a spatial predicate to a GetFeature request entity. If the given geometry element has no spatial reference (srsName) it is assumed to use the default CRS specified in the capabilities document.

Parameters:

request - The request entity (wfs:GetFeature).

spatialOp - The name of a spatial operator.

gmlGeom - A DOM Element representing a GML geometry.

valueRef - An Element (fes:ValueReference) that specifies the spatial property to check. If it is null, the predicate applies to all spatial properties.
