Constructor Detail

DefaultPolygon

public DefaultPolygon(String id,
                      CRS crs,
                      PrecisionModel pm,
                      Ring exteriorRing,
                      List<Ring> interiorRings)

Creates a new DefaultPolygon instance from the given parameters.

Parameters:

id - identifier, may be null

crs - coordinate reference system, may be null

pm - precision model, may be null

interiorRings - list of rings that define the inner boundaries, may be empty or null

Method Detail

getExteriorRing

public Ring getExteriorRing()

Description copied from interface: Polygon

Returns the exterior ring of the polygon.

Please note that this method may return null. The following explanation is from the GML 3.1.1 spec (section 9.2.2.5): In the normal 2D case, one of these rings is distinguished as being the exterior boundary. In a general manifold this is not always possible, in which case all boundaries shall be listed as interior boundaries, and the exterior will be empty.

Specified by:

getExteriorRing in interface Polygon

Returns:

the exterior ring, or null if no ring is distinguished as being the exterior boundary

getInteriorRings

public List<Ring> getInteriorRings()

Description copied from interface: Polygon

Returns the interior rings (holes) of the polygon.

Specified by:

getInteriorRings in interface Polygon

Returns:

the interior rings (holes) of the polygon, list may be empty (but not null)

getSurfaceType

public Surface.SurfaceType getSurfaceType()

Description copied from interface: Surface

Returns the type of surface.

Specified by:

getSurfaceType in interface Polygon

Specified by:

getSurfaceType in interface Surface

Overrides:

getSurfaceType in class DefaultSurface

Returns:

the type of surface

getPatches

public List<PolygonPatch> getPatches()

Description copied from interface: Surface

Returns the patches that constitute this surface.

Specified by:

getPatches in interface Polygon

Specified by:

getPatches in interface Surface

Overrides:

getPatches in class DefaultSurface

Returns:

the patches that constitute this surface

buildJTSGeometry

protected com.vividsolutions.jts.geom.Geometry buildJTSGeometry()

Overrides:

buildJTSGeometry in class DefaultSurface
