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

                     
                     
                     while (dl.hasNext()) {
                          Duration duration = dl.getNextDuration();
                     }
                     
                                 
                     
                

                     
                     
                     while dl.hasNext()) {
                          Duration[] durations = dl.getNextDurations(dl.available());
                     }
