Class GeoPoint


  • public class GeoPoint
extends Geometry
    The GeoPoint class is derived from the Geometry class.

    This class is mainly used to model point geographic entity.

    Point2D and GeoPoint can be used to represent 2D points, the different is GeoPoint describes the feature entity, Point2D describes a location point; GeoPoint with different styles can represent different feature entities, Point2D is widely used to locate coordinates. When the object of this class has been released by the dispose() method, a ObjectDisposedException will throw out when call the method of this object.
