  • Method Details

    • connectedComponentFinished

      void connectedComponentFinished(ConnectedComponentTraversalEvent e)
      Called to inform listeners that the traversal of the current connected component has finished.
      Parameters:
      e - the traversal event.
    • connectedComponentStarted

      void connectedComponentStarted(ConnectedComponentTraversalEvent e)
      Called to inform listeners that a traversal of a new connected component has started.
      Parameters:
      e - the traversal event.
    • edgeTraversed

      void edgeTraversed(EdgeTraversalEvent<V,E> e)
      Called to inform the listener that the specified edge have been visited during the graph traversal. Depending on the traversal algorithm, edge might be visited more than once.
      Parameters:
      e - the edge traversal event.
    • vertexTraversed

      void vertexTraversed(VertexTraversalEvent<V> e)
      Called to inform the listener that the specified vertex have been visited during the graph traversal. Depending on the traversal algorithm, vertex might be visited more than once.
      Parameters:
      e - the vertex traversal event.
    • vertexFinished

      void vertexFinished(VertexTraversalEvent<V> e)
      Called to inform the listener that the specified vertex have been finished during the graph traversal. Exact meaning of "finish" is algorithm-dependent; e.g. for DFS, it means that all vertices reachable via the vertex have been visited as well.
      Parameters:
      e - the vertex traversal event.
