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

while (crpl.hasNext()) {
     CourseRegistrationPeer peer = crpl.getNextCourseRegistrationPeer();
}
                

while (crpl.hasNext()) {
     CourseRegistrationPeer[] peers = crpl.getNextCourseRegistrationPeers(crpl.available());
}
