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

                     
                     
                     while (bnl.hasNext()) {
                          BillingNode node = bnl.getNextBillingNode();
                     }
                     
                                 
                     
                

                     
                     
                     while (bnl.hasNext()) {
                          BillingNode[] nodes = bnl.getNextBillingNodes(bnl.available());
                     }
