Interface Polygon

All Superinterfaces:

Geometry, Surface

All Known Implementing Classes:

SePolygon

public interface Polygon
extends Surface

The Polygon interface defines the methods for a class whose instances create a geometric object which is defined by 1 exterior boundary and 0 or more interior boundaries.

Method Summary

Linestring	exteriorRing() Returns the exterior ring of a polygon as a linestring.
Linestring	interiorRingN(int n) Returns the nth interior ring of a polygon as a linestring.
int	numInteriorRings() Numinteriorrings takes a polygon and returns the number of its interior rings.

Method Detail

exteriorRing

Linestring exteriorRing()
                        throws GeometryException

Returns the exterior ring of a polygon as a linestring.

Throws:

GeometryException

numInteriorRings

int numInteriorRings()
                     throws GeometryException

Numinteriorrings takes a polygon and returns the number of its interior rings.

Throws:

GeometryException

interiorRingN

Linestring interiorRingN(int n)
                         throws GeometryException

Returns the nth interior ring of a polygon as a linestring. The order of the rings cannot be predefined since the rings are organized according to the rules defined by the internal geometry verification routines and not by geometric orientation.

Throws:

GeometryException
