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

                     
                     
                     while (qcl.hasNext()) {
                          QueueConstrainer constrainer = qcl.getNextQueueConstrainer();
                     }
                     
                                 
                     
                

                     
                     
                     while qscl.hasNext()) {
                          QueueConstrainer[] constrainers = qcl.getNextQueueConstrainers(qcl.available());
                     }
