public class FXBendOnSegmentHandleDragPolicy
extends AbstractFXOnDragPolicy

The FXBendOnSegmentHandleDragPolicy is an AbstractFXOnDragPolicy that can be installed on the handle parts of an FXConnection, so that the user is able to manipulate that connection by dragging its handles. This policy expects that a handle is created for each anchor point of the connection (start, way, end), as well as for each middle point of a segment. Moreover, this policy expects that the respective handles are of type FXCircleSegmentHandlePart.
