Field Detail

### counter

    private final int[] counter

  Multidimensional counter.

### count

    private int count

  Unidimensional counter.

Constructor Detail

### MultidimensionalCounter.Iterator

    MultidimensionalCounter.Iterator()

  Create an iterator

  See Also:
    `MultidimensionalCounter.iterator()`

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`.

### 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`
