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

while (arpl.hasNext()) {
     ActivityRegistrationPeer peer = arpl.getNextActivityRegistrationPeer();
}            
                

while (arpl.hasNext()) {
     ActivityRegistrationPeer[] peers = arpl.getNextActivityRegistrationPeers(arpl.available());
}
