Class EdgeShape<V,​E>

  • Type Parameters:
    V - the vertex type
    E - the edge type
    public class EdgeShape<V,​E>
extends java.lang.Object
    An interface for decorators that return a Shape for a specified edge. All edge shapes must be defined so that their endpoints are at (0,0) and (1,0). They will be scaled, rotated and translated into position by the PluggableRenderer.

      Nested Classes 
      Modifier and Type Class Description
      class  EdgeShape.BentLine
      An edge shape that renders as a bent-line between the vertex endpoints.
      class  EdgeShape.Box
      An edge shape that renders as a diamond with its nadir at the center of the vertex.
      class  EdgeShape.CubicCurve
      An edge shape that renders as a CubicCurve between vertex endpoints.
      class  EdgeShape.Line
      An edge shape that renders as a straight line between the vertex endpoints.
      class  EdgeShape.Loop
      An edge shape that renders as a loop with its nadir at the center of the vertex.
      class  EdgeShape.Orthogonal
      An edge shape that renders as a bent-line between the vertex endpoints.
      class  EdgeShape.QuadCurve
      An edge shape that renders as a QuadCurve between vertex endpoints.
      class  EdgeShape.SimpleLoop
      An edge shape that renders as a loop with its nadir at the center of the vertex.
      class  EdgeShape.Wedge
      An edge shape that renders as an isosceles triangle whose apex is at the destination vertex for directed edges, and as a "bowtie" shape for undirected edges.
