Interface PvGeometryIf

public interface PvGeometryIf

Interface to container geometry used in JavaView displays. Methods specified in this interface are used to transfer data from a geometry class to the display in the geometry's paint method. Each subclass of jv.project.PgGeometry should derive or implement a method paint(PvGeometryIf dc) in which methods of this interface are called to transfer data to container in display.
