LineValidator

```
public interface LineValidator
```
This is the interface for validators for a String read by the Reader in the CSVReader before it is processed.
This should only be used if you have a very good understanding and full control of the data being processed.

Since this is working on an individual line it may not be a full record if an element has a newline character in it.

Since:
