or YAML. The :class:`Symfony\\Component\\Serializer\\Mapping\\Factory\\ClassMetadataFactory`
that will be used by the normalizer must be aware of the format to use.

Initialize the :class:`Symfony\\Component\\Serializer\\Mapping\\Factory\\ClassMetadataFactory`
like the following::
The following code shows how to initialize the :class:`Symfony\\Component\\Serializer\\Mapping\\Factory\\ClassMetadataFactory`
for each format:

* Annotations in PHP files::

use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
// For annotations
use Doctrine\Common\Annotations\AnnotationReader;
use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
use Symfony\Component\Serializer\Mapping\Loader\AnnotationLoader;
// For XML
// use Symfony\Component\Serializer\Mapping\Loader\XmlFileLoader;
// For YAML
// use Symfony\Component\Serializer\Mapping\Loader\YamlFileLoader;

$classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
// For XML
// $classMetadataFactory = new ClassMetadataFactory(new XmlFileLoader('/path/to/your/definition.xml'));
// For YAML
// $classMetadataFactory = new ClassMetadataFactory(new YamlFileLoader('/path/to/your/definition.yml'));

* XML files::

use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
use Symfony\Component\Serializer\Mapping\Loader\XmlFileLoader;

$classMetadataFactory = new ClassMetadataFactory(new XmlFileLoader('/path/to/your/definition.xml'));

* YAML files::

use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
use Symfony\Component\Serializer\Mapping\Loader\YamlFileLoader;

$classMetadataFactory = new ClassMetadataFactory(new YamlFileLoader('/path/to/your/definition.yml'));
