Constructor Detail

SurfaceReference

public SurfaceReference(GMLReferenceResolver resolver,
                        String uri,
                        String baseURL)

Creates a new SurfaceReference instance.

Parameters:

resolver - used for resolving the reference, must not be null

uri - the geometry's uri, must not be null

baseURL - base URL for resolving the uri, may be null (no resolving of relative URLs)

Method Detail

getArea

public Measure getArea(Unit requestedBaseUnit)

Specified by:

getArea in interface Surface

Returns:

area of the surface

getSurfaceType

public Surface.SurfaceType getSurfaceType()

Description copied from interface: Surface

Returns the type of surface.

Specified by:

getSurfaceType in interface Surface

Returns:

the type of surface

getCentroid

public Point getCentroid()

Description copied from interface: Geometry

Returns the centroid of the geometry.

Specified by:

getCentroid in interface Geometry

Overrides:

getCentroid in class GeometryReference<T extends Surface>

Returns:

a Point that is the centroid of this geometry

getExteriorRingCoordinates

public Points getExteriorRingCoordinates()

Description copied from interface: Surface

Convenience method for accessing the control points of the exterior ring of a simple polygon surface.

NOTE: This method is only safe to use when the surface consists of a single planar patch that has a linear interpolated exterior ring.

Specified by:

getExteriorRingCoordinates in interface Surface

Returns:

the control points

getInteriorRingsCoordinates

public List<Points> getInteriorRingsCoordinates()

Description copied from interface: Surface

Convenience method for accessing the control points of the interior rings of a simple polygon surface.

NOTE: This method is only safe to use when the surface consists of a single planar patch that has linear interpolated interior rings.

Specified by:

getInteriorRingsCoordinates in interface Surface

Returns:

the control points

getPatches

public List<? extends SurfacePatch> getPatches()

Description copied from interface: Surface

Returns the patches that constitute this surface.

Specified by:

getPatches in interface Surface

Returns:

the patches that constitute this surface

getPerimeter

public Measure getPerimeter(Unit requestedUnit)

Specified by:

getPerimeter in interface Surface

Returns:

perimeter of the surface
