          public Iterator<String> iterator()

      Specified by:
        `iterator` in interface `Iterable<String>`

    - #### get

          public String get(int index)

      Description copied from interface: `Path`
      Get a particular segment within this path.
      Specified by:
        `get` in interface `Path`
      Parameters:
        `index` - the 0-based index of the segment in this path
      Returns:
        the segment; never null

    - #### getLast

          public String getLast()

      Description copied from interface: `Path`
      Get the last segment in the path.
      Specified by:
        `getLast` in interface `Path`
      Returns:

    - #### getFirst

          public String getFirst()

      Description copied from interface: `Path`
      Get the first segment in the path.
      Specified by:
        `getFirst` in interface `Path`
      Returns:
