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

                     
                     
                     while (nl.hasNext()) {
                          Node node = nl.getNextNode();
                     }
                     
                                 
                     
                

                     
                     
                     while (nl.hasNext()) {
                          Node[] nodes = nl.getNextNodes(nl.available());
                     }
