    • validate

      public void validate(Field field, Void constraintValue, MessageFormatter formatter, String value) throws ValidationException
      Description copied from interface: Validator
      Invoked after the client-submitted value has been translated to check that the value conforms to expectations (often, in terms of minimum or maximum value). If and only if the value is approved by all Validators is the value applied by the field.
      Parameters:
      field - the field for which a client submitted value is being validated
      constraintValue - the value used to constrain
      formatter - Validation messages, in the appropriate locale
      value - the translated value supplied by the user
      Throws:
      ValidationException - if the value violates the constraint
