Class Validator<E extends RuntimeException>

  com.faunos.util.Validator<E>

public class Validator<E extends RuntimeException>
extends Object

A validation and exception raising factory. This only works if the exception to be thrown is an unchecked exception. The idea is that the indirection provides a centralized place for code to reconfigure the type of exceptions thrown.
