Detailed Description
Class to handle the procedures for dumping the contents of a data table into a CSV file. This allows the use of constraint attributes. Only one occurence of a unique combination of the list of contraints will be output.
Constructor & Destructor Documentation
| DataDumper::DataDumper | ( | const TableInfo & | aInfo | ) |
