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).
