public class ConnectionBendpointTracker extends SimpleDragTracker
A tracker for creating new bendpoints or dragging existing ones. The Connection bendpoint tracker is returned by connection bendpoint handles. This tracker will send aBendpointRequest
to the connection editpart which originated the tracker. The bendpoint request may be either a request to move an existing bendpoint, or a request to create a new bendpoint.A ConnectionBendpointTracker operates on a single connection editpart.
