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

                     
                     
                     while (pnl.hasNext()) {
                          PollsNode node = pnl.getNextPollsNode();
                     }
                     
                                 
                     
                

                     
                     
                     while (pnl.hasNext()) {
                          PollsNode[] nodes = pnl.getNextPollsNodes(pnl.available());
                     }
