    `void` | `render(Field field, Long constraintValue, MessageFormatter formatter, MarkupWriter writer, FormSupport formSupport)` Hook used by components to allow the validator to contribute additional attributes or (more often) client-side JavaScript (via the `FormSupport.addValidation(Field, String, String, Object)`).
    `void` | `validate(Field field, Long constraintValue, MessageFormatter formatter, Number value)` 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).

        `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

    - #### render

          public void render(Field field,
                             Long constraintValue,

      Parameters:
        `field` - the field which is currently being rendered
        `constraintValue` - the value used to constrain input
        `formatter` - validation message, in the appropriate locale
        `writer` - markup writer, allowing additional attributes to be written into the active element
        `formSupport` - used to add JavaScript
