- * data within one class. Developers should ensure that all reading is done
- * before returning from the read() method. This is to ensure all data has been
- * read first, before beginning to process. It is possibly detrimental to
- * performance if processing begins when records still need to be read, because
- * any writing of output will put the transaction in a volatile state, since
- * errors with any additional input will need to cause a rollback, rather than
- * simply skipping that record.
