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

                     
                     
                     while (arl.hasNext()) {
                          ActivityRegistration registration = arl.getNextActivityRegistration();
                     }
                     
                                 
                     
                

                     
                     
                     while (arl.hasNext()) {
                          ActivityRegistration[] registrations = arl.getNextActivityRegistrations(arl.available());
                     }
