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

                     
                     
                     while (aul.hasNext()) {
                          ActivityUnit unit = aul.getNextActivityUnit();
                     }
                     
                                 
                     
                

                     
                     
                     while (aul.hasNext()) {
                          ActivityUnit[] units = aul.getNextActivityUnits(aul.available());
                     }
