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

                     
                     
                     while (sl.hasNext()) {
                          System system = sl.getNextSystem();
                     }
                     
                                 
                     
                

                     
                     
                     while (sl.hasNext()) {
                          System[] systems = sl.getNextSystems(sl.available());
                     }
