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>
