Method Summary

Modifier and Type	Method and Description
public void	copyStateFrom(RegionIterator ri) Copies the iteration state from this RegionIterator object into another RegionIterator object to allow multiple iteration branches from the current position.
public RegionIterator	createCopy() Returns a new RegionIterator object representing the same iteration state as this object to allow multiple iteration branches from the current position.
public boolean	nextXBand(int[] range) Moves the iteration state to the beginning of the next X band in the current Y range returning true if one is found and recording the low and high X coordinates of the range in the array at locations 0 and 2 respectively.
public boolean	nextYRange(int[] range) Moves the iteration state to the beginning of the next Y range in the region returning true if one is found and recording the low and high Y coordinates of the range in the array at locations 1 and 3 respectively.
