selected key removal

We often see the idiom:

Iterator itr = selector.selectedKeys().iterator();

while (itr.hasNext()){

SelectionKey key = (SelectionKey)itr.next();

itr.remove();

...// process the 'key'

...

}

Does this Iterator.remove() call remove the key from selector's selected key set or does it only remove the key from a copy of the set? In other words, should we have to call key.cancel() to really remove it from the selector's key set?
