public class PgGeometry
extends PsObject
implements PgGeometryIf, java.lang.Cloneable

Abstract class for all geometry classes in JavaView, and implementation of PgGeometryIf. Users may derive their own geometry classes either from this class resp. its subclasses, or by writing a class implementing the interface PgGeometryIf. Either of the two options is required to view the geometry in a JavaView display.
