Interface RowProcessor

public interface RowProcessor
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.
