  • Method Details

    • hasNext

      boolean hasNext()
      Returns true if the iteration has more vertices. If it returns true, the next() method would return a vertex rather than throwing an exception.
      Returns:
      true if the iteration has more vertices.

    • next

      int next()
      Returns the next vertex in the iteration.
      Returns:
      the next vertex in the iteration.
      Throws:
      NoSuchElementException - if the iteration has no more vertices.

    • setWeight

      void setWeight(double weight)
      Parameters:
      weight - the weight to be set for the current vertex.

    • getWeight

      double getWeight()
      Returns:
      the weight of the current vertex.

    • setLabel

      void setLabel(V label)
      Parameters:
      label - the label to be set for the current vertex.

    • getLabel

      V getLabel()
      Returns:
      the label of the current vertex.

    • remove

      void remove()
      Removes the current vertex from the graph.
