All Implemented Interfaces:

Immutable, ShpShape

public class ShpPolygon
extends java.lang.Object
implements ShpShape

ESRI's multiple part (ring) polygon in (x, y) space.

By our definitions, a shapefile Polygon entity is really a list of polygon objects. Each of these is stored as a series of connected vertices.
