diva.canvas.connector.ConnectorManipulator
A manipulator which attaches grab handles to the ends of a connector. The interactor given to the grab-handles determines the behaviour of the grab-handles. @author John Reekie @author Michael Shilman @version $Id: ConnectorManipulator.java,v 1.14 2005/07/08 19:54:50 cxh Exp $
