Interface RowValidator

All Known Implementing Classes:
RowFunctionValidator, RowMustHaveSameNumberOfColumnsAsFirstRowValidator
public interface RowValidator
This is the interface for validators for an array of Strings read by the CSVReader after it is processed. This should only be used if you have a very good understanding and full control of the data being processed. Good examples of a RowValidator would be to ensure the number of columns in the row or, if you know what data are in which column, check the format and type of data.
