  • Method Details

    • calculateHandleLocation

      Point2D calculateHandleLocation(CyNetworkView netView, View<CyEdge> edgeView)
      Calculate absolute position of this handle for the given edge view.
      Parameters:
      netView - graph view for this handle
      edgeView - The handle belongs to this edge view.
      Returns:
      Absolute position of this handle in the network view.

    • defineHandle

      void defineHandle(CyNetworkView netView, View<CyEdge> edgeView, double x, double y)
      Define this handle. Handle will be described as a relative location from source and target node. NOTE: in the implementation, the given (x, y) values will be converted to relative position. The conversion equation is exchangeable.
      Parameters:
      netView - graph view for this handle
      edgeView - The handle belongs to this edge view.
      x - Absolute value for X-location.
      y - Absolute value for Y-location.

    • getSerializableString

      String getSerializableString()
