package com.opencsv.processor;


This is the interface for processors for an array of Strings read by the CSVReader before> they are validated.

This should only be used if you have a very good understanding and full
control of the data being processed or something you want applied to every
column in the row.


WARNING - using a processor can change the string in ways that could make
it impossible to be processed or make it into a different format than what
you are expecting based on the settings of the parser and reader. So great
care must be taken when creating and using a RowProcessor.


NOTE - Because of the potential problems a bad processor can cause we
will close down any bug reports created for opencsv where a RowProcessor is
involved with the recommendation they be reopened as a support request.

While not called directly by opencsv it is in the interface to provide an easy way to test
if the processor is functioning properly.

Params:
