public CSVProcessor(MasterReport report)
             throws ReportProcessingException

Creates a new CSVProcessor. The processor will use a comma (",") to separate the column values, unless defined otherwise in the report configuration. The processor creates a private copy of the clone, so that no change to the original report will influence the report processing. DataRow names are not written.

Parameters:

report - the report to be processed.

Throws:

ReportProcessingException - if the report initialisation failed.
