  • Field Details

    • hollowTargetArrowShape

      public boolean hollowTargetArrowShape

    • hollowSourceArrowShape

      public boolean hollowSourceArrowShape

  • Constructor Details

    • LineEdgeShape

      public LineEdgeShape()
      The constructor creates a line using default values. The shapes of the source and target nodes are given to enable the edge to paint itself correctly between those nodes. The line is painted between the centers of the source and target shape. No arrows are painted.
