| 5 | * The following methods have been added to the base dataformat class to allow instances to export to a local | |
| 6 | file. They can be overridden in extending classes to define how files should be created: | |
| 7 | - start_output_to_file() | |
| 8 | - close_output_to_file() | |

12 | been removed from core dataformat plugins and have been replaced. |
| 13 | - write_header() has been replaced with the two functions start_output() and start_sheet(). | |
| 14 | - write_footer() has been replaced with the two functions close_output() and close_sheet(). | |

15 | For backwards compatibility write_header() and write_footer() will continue to work but if used will |
| 16 | trigger the function error_log(). | |
