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

                     
                     
                     while (gl.hasNext()) {
                          Grade grade = gl.getNextGrade();
                     }
                     
                                 
                     
                

                     
                     
                     while (gl.hasNext()) {
                          Grade[] grades = gl.getNextGrades(gl.available());
                     }
