Method Detail

createCoordinateList

public List<Coordinate> createCoordinateList(org.geotoolkit.gml.xml.AbstractGeometry gmlGeom)

Description copied from interface: CoordinateListFactory

Creates a list of coordinates from a GML geometry representation. The sequence typically includes the constituent vertices.

Specified by:

createCoordinateList in interface CoordinateListFactory

Parameters:

gmlGeom - A GML geometry object (constructed from its XML representation).

Returns:

A list of 2D coordinates that constitute the geometry.

createCoordinateList

public List<Coordinate> createCoordinateList(Element gmlSurface)

Creates a list of coordinates on the exterior boundary of a GML surface geometry.

Parameters:

gmlSurface - A gml:Surface or gml:Polygon element (including extension elements that can substitute for gml:Surface).

Returns:

A list of 2D coordinates.

interiorCoordinatesSet

public Set<List<Coordinate>> interiorCoordinatesSet(org.geotoolkit.gml.xml.AbstractGeometry gmlGeom)

Returns a set containing sequences of points on the interior boundaries of a surface geometry. Each list in the set corresponds to a distinct interior boundary.

Parameters:

gmlGeom - A GML surface geometry (substitutes for gml:AbstractSurface).

Returns:

A set of Coordinate lists representing interior boundary curves; it may be empty.

interiorCoordinatesSet

public Set<List<Coordinate>> interiorCoordinatesSet(Element gmlSurface)

Returns a set containing sequences of points on the interior boundaries of a surface geometry. Each list in the set corresponds to a distinct interior boundary.

Parameters:

gmlSurface - A GML surface geometry (or an element in its substitution group).

Returns:

A set of Coordinate lists representing interior boundary curves; it may be empty.

exteriorBoundaryOfSurface

List<Coordinate> exteriorBoundaryOfSurface(org.geotoolkit.gml.xml.v321.SurfacePatchArrayPropertyType patchArray,
                                         String srsName)

Returns a list of points on the exterior boundary of a Surface geometry. The constituent patches are merged.

Parameters:

patchArray - An array property containing a sequence of surface patches; it corresponds to the gml:patches element.

srsName - A CRS identifier that applies to the surface patches.

Returns:

A list of Coordinate objects representing a boundary curve (ring).

exteriorBoundaryOfPolygon

List<Coordinate> exteriorBoundaryOfPolygon(org.geotoolkit.gml.xml.v321.PolygonType gmlPolygon)

Returns a list of points on the exterior boundary of a Polygon geometry.

Parameters:

gmlPolygon - A gml:Polygon geometry instance.

Returns:

A list of Coordinate objects representing a boundary curve.

interiorBoundariesOfPolygon

Set<List<Coordinate>> interiorBoundariesOfPolygon(org.geotoolkit.gml.xml.v321.PolygonType gmlPolygon)

Returns a set containing sequences of points on the interior boundaries of a Polygon geometry.

Parameters:

gmlPolygon - A gml:Polygon geometry instance.

Returns:

A set of Coordinate lists representing interior boundary curves.

interiorBoundariesOfSurface

Set<List<Coordinate>> interiorBoundariesOfSurface(org.geotoolkit.gml.xml.v321.SurfacePatchArrayPropertyType patchArray,
                                                String srsName)

Returns a set containing sequences of points on the interior boundary curves of a Surface geometry.

Parameters:

patchArray - An array property containing a sequence of surface patches; it corresponds to the gml:patches element.

srsName - A CRS identifier that applies to the surface patches.

Returns:

A set of Coordinate lists representing interior boundary curves.
