Interface EdgeIterator<E>

Type Parameters:
E - the type of edge labels.
All Superinterfaces:
Iterator<Edge<E>>
public interface EdgeIterator<E> extends Iterator<Edge<E>>
An iterator over all the edges of a graph. In order to iterate over the edges incident with a specific vertex use Graph.neighborIterator(int).

  • Method Details

    • hasNext

      boolean hasNext()
      Returns true if the iteration has more edges. If it returns true, the next() method would return an edge rather than throwing an exception.
      Specified by:
      hasNext in interface Iterator<E>
      Returns:
      true if the iteration has more edges.

    • next

      Edge<E> next()
      Returns the next edge in the iteration.
      Specified by:
      next in interface Iterator<E>
      Returns:
      the next edge in the iteration.
      Throws:
      NoSuchElementException - if the iteration has no more edges.

    • setWeight

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

    • getWeight

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

    • setData

      void setData(int dataType, double value)

    • incData

      void incData(int dataType, double amount)

    • getData

      double getData(int dataType)

    • getData

      double getData(int dataType, double defaultValue)

    • setLabel

      void setLabel(E label)
      Parameters:
      label - the label to be set for the current edge.

    • getLabel

      E getLabel()
      Returns:
      the label of the current edge.

    • remove

      void remove()
      Removes the current edge from the graph.
      Specified by:
      remove in interface Iterator<E>
