is a :class:`Symfony\\Component\\Validator\\ConstraintViolation` object,
which holds the error message on its ``getMessage`` method.

Using the Validator outside the Symfony framework context
---------------------------------------------------------

The Symfony ``validator`` can be used outside Symfony framework thanks to the :class: `Symfony\Component\Validator\ValidatorBuilder`:

use Symfony\Component\Validator\ValidatorBuilder;

$validator = (new ValidatorBuilder())
->addMethodMapping('loadValidatorMetadata')
->getValidator();

The ValidatorBuilder accept also Yaml or Xml mappings, you only need to set up the ``addXmlMapping/addYamlMapping`` methods with the correct path to the file. To enable the annotations, the method ``enableAnnotationMapping`` is available.
