Class TINValidator

java.lang.Object
org.apache.commons.validator.routines.TINValidator
public class TINValidator extends Object
Tax identification number (TIN) Validator.

The validator includes a default set of formats and check routines for countries

This can be adjusted f.i. adding a new country routines by creating a validator and using the setValidator(String, int, String, CheckDigit) method to add (or remove) an entry.

For example: 

 TINValidator v = new TINValidator();
 v.setValidator("AT", 9, "\\d{9}", TidATCheckDigit.getInstance());

The singleton default instance cannot be modified in this way.

Since:
1.10.0
