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.
