public class mxGraphHierarchyEdge extends mxGraphAbstractHierarchyCell
An abstraction of a hierarchical edge for the hierarchy layout

  • Field Details

    • edges

      public List<Object> edges
      The graph edge(s) this object represents. Parallel edges are all grouped together within one hierarchy edge.

    • source

      public mxGraphHierarchyNode source
      The node this edge is sourced at

    • target

      public mxGraphHierarchyNode target
      The node this edge targets

    • isReversed

      protected boolean isReversed
      Whether or not the direction of this edge has been reversed internally to create a DAG for the hierarchical layout

  • Constructor Details

    • mxGraphHierarchyEdge

      public mxGraphHierarchyEdge(List<Object> edges)
      Constructs a hierarchy edge
      Parameters:
      edges - a list of real graph edges this abstraction represents

  • Method Details

    • invert

      public void invert()

    • isReversed

      public boolean isReversed()
      Returns:
      Returns the isReversed.

    • setReversed

      public void setReversed(boolean isReversed)
