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

                     
                     
                     while (gsl.hasNext()) {
                          GradeSystem system = gsl.getNextGradeSystem();
                     }
                     
                                 
                     
                

                     
                     
                     while (gsl.hasNext()) {
                          GradeSystem[] systems = gsl.getNextGradeSystems(gsl.available());
                     }
