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

while qscel.hasNext()) {
     QueueConstrainerEnabler enabler = qcel.getNextQueueConstrainerEnabler();
}            
                

while (qcel.hasNext()) {
     QueueConstrainerEnabler[] enablers = qcel.getNextQueueConstrainerEnablers(qcel.available());
}
