  • Method Details

    • visit

      int visit(Graphable element, GraphTraversal traversal)
      Visits a graph component.
      Parameters:
      element - The component being visited.
      traversal - The traversal controlling the sequence of graph component visits.
      Returns:
      GraphTraversal#CONTINUE to signal that the traversal should continue.
      GraphTraversal#CONTINUE to signal that the traversal should suspend.
      GraphTraversal#KILL_BRANCH to signal that the traversal should kill its current branch.
      GraphTraversal#STOP to signal that the traversal should stop.

    • finish

      void finish()
      Called when the graph traversal is completed. Whether this method is called after a traversal has been stopped with a return signal is up to the implementation of GraphTraversal.
