Interface UniquenessConstraints

public interface UniquenessConstraints

JSR 303 validation group for Permazen uniqueness constraints.

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
