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

                     
                     
                     while (rl.hasNext()) {
                          Receipt receipt = rl.getNextReceipt();
                     }
                     
                                 
                     
                

                     
                     
                     while (rl.hasNext()) {
                          Receipt[] receipts = rl.getNextReceipts(rl.available());
                     }
