Note: The number returned by this method may differ from the number of nodes actually returned by calls to hasNext() / getNextNode()! This is because this iterator works on a lazy instantiation basis and while iterating over the nodes some of them might have been deleted in the meantime. Those will not be returned by getNextNode(). As soon as an invalid node is detected, the size of this iterator is adjusted.
