public interface Geometry

The Geometry interface defines the methods for the Geometry subclasses. Geometry is the root class of the hierarchy and is an abstract, non-instantiable class. Only the subclasses of Geometry are instantiable. The instances of the subclasses of Geometry create zero, one and two-dimensional geometric objects that exist in two-dimensional coordiante space.
