Like all OsidLists, SpatialUnitList provides a means for accessing SpatialUnit elements sequentially either one at a time or many at a time. Examples:

                     
                     
                     while (sul.hasNext()) {
                          SpatialUnit unit = sul.getNextSpatialUnit();
                     }
                     
                                 
                     
                

                     
                     
                     while (sul.hasNext()) {
                          SpatialUnit[] units = sul.getNextSpatialUnits(sul.available());
                     }
