 * 
 * Explicit use of this class only needed if you wish to manually trigger validation of uniqueness constraints only,
 * for example:
 *  
 *  user.setUsername(u);
 *  user.revalidate(UniquenessConstraints.class);
 *  user.getTransaction().validate();           // throws exception if 'u' is not unique
 *

 * @see PermazenObject#revalidate PermazenObject.revalidate()
