Validator (Identity4J Utils 1.2.2 API)

All Known Implementing Classes:

AbstractSingleValueValidator, BooleanValidator, ColorValidator, DateValidator, DnValidator, EmailAddressValidator, FileValidator, IntegerValidator, IpAddressValidator, ListValidator, RegexValidator, StringValidator, UrlValidator
```
public interface Validator
```
A validator for application-specific objects.
This interface is totally divorced from any infrastructure or context; that is to say it is not coupled to validating only objects in the web tier, the data-access tier, or the whatever-tier. As such it is amenable to being used in any layer of an application, and supports the encapsulation of validation logic as first-class citizens in their own right.
