- - ### Method Detail

    - #### hasNext

          public boolean hasNext()

      Specified by:
        `hasNext` in interface `Iterator<Integer>`

    - #### next

          public Integer next()

      Specified by:
        `next` in interface `Iterator<Integer>`
      Returns:
        the unidimensional count after the counter has been incremented by `1`.
      Throws:
        `NoSuchElementException` - if `hasNext()` would have returned `false`.

    - #### getCount

          public int getCount()

      Get the current unidimensional counter slot.
      Returns:
        the index within the unidimensionl counter.

    - #### getCounts

          public int[] getCounts()

      Get the current multidimensional counter slots.
      Returns:
        the indices within the multidimensional counter.

    - #### getCount

          public int getCount(int dim)

      Get the current count in the selected dimension.
      Parameters:
        `dim` - Dimension index.
      Returns:
        the count at the corresponding index for the current state of the iterator.
      Throws:
        `IndexOutOfBoundsException` - if `index` is not in the correct interval (as defined by the length of the argument in the `constructor of the enclosing class`).

    - #### remove

          public void remove()

      Specified by:
        `remove` in interface `Iterator<Integer>`
      Throws:
        `UnsupportedOperationException`
