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

                     
                     
                     while (sl.hasNext()) {
                          Symmary summary = sl.getNextSummary();
                     }
                     
                                 
                     
                

                     
                     
                     while (sl.hasNext()) {
                          Summary[] summaries = sl.getNextSummaries(sl.available());
                     }
