LayoutIterator Class Reference
#include <LayoutIterator.H>
Detailed Description
An Iterator based on a BoxLayout object.An Iterator based on a BoxLayout object. It does not support a dereferencing operation(1), since it is intended to work with all of BoxLayouts, DisjointBoxLayouts, BoxLayoutDatas LevelData's, and any object that is built on top of a BoxLayout object. LayoutIterator accesses the data in a BoxLayout-based object in a NON-data-parallel manner (i.e. every processor iterates through all the Boxes in the BoxLayout). This differs from the DataIterator class.
BoxLayout-based objects can act as the Factory for the LayoutIterator.
(1) STL-speak. not critical for comprehension, but can help people familiar with STL iterators and expecting similar behaviour.
