    - #### HadoopEdge

          public HadoopEdge(Edge edge,
                            HadoopGraph graph)

  - ### Method Detail

    - #### getBaseEdge

          public Edge getBaseEdge()

      Specified by:
        `getBaseEdge` in interface `WrappedEdge<Edge>`

    - #### vertices

          public Iterator<Vertex> vertices(Direction direction)

      Description copied from interface: `Edge`
      Retrieve the vertex (or vertices) associated with this edge as defined by the direction. If the direction is `Direction.BOTH` then the iterator order is: `Direction.OUT` then `Direction.IN`.
      Specified by:
        `vertices` in interface `Edge`
      Parameters:
        `direction` - Get the incoming vertex, outgoing vertex, or both vertices
      Returns:
        An iterator with 1 or 2 vertices

    - #### properties

          public <V> Iterator<Property<V>> properties(String... propertyKeys)

      Description copied from interface: `Edge`
      Get an `Iterator` of properties.
      Specified by:
        `properties` in interface `Edge`
      Specified by:
        `properties` in interface `Element`
