Add a max depth option during the normalization process. Especially useful when normalizing trees.
Usage:
```php
use Symfony\Component\Serializer\Annotation\MaxDepth;
class MyObj
{
/**
* @MaxDepth(2)
*/
public $foo;
/**
* @var self
*/
public $child;
}
use Doctrine\Common\Annotations\AnnotationReader;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Mapping\Loader\AnnotationLoader;
use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
$classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
$normalizer = new ObjectNormalizer($classMetadataFactory);
$serializer = new Serializer(array($this->normalizer));
$level1 = new MyObj();
$level1->foo = 'level1';
$level2 = new MyObj();
$level2->foo = 'level2';
$level1->child = $level2;
$level3 = new MyObj();
$level3->foo = 'level3';
$level2->child = $level3;
$result = $serializer->normalize($level1, null, array(ObjectNormalizer::ENABLE_MAX_DEPTH => true));
/* $result = array(
'foo' => 'level1',
'child' => array(
'foo' => 'level2',
'child' => array(
'child' => null,
),
),
);
*/
```
* [x] Metadata support
* [x] `@MaxDepth(2)` annotation and loader
* [x] XML loader
* [x] YAML loader
* [x] Delegate recursive normalization at the end of the process
* [x] Use constants with Late Static Binding in the abstract class instead of raw strings
* [x] Move common logic to the abstract class

Serializer Component
With the Serializer component it's possible to handle serializing data structures, including object graphs, into array structures or other formats like XML and JSON. It can also handle deserializing XML and JSON back to object graphs.
Resources
You can run the unit tests with the following command:
$ cd path/to/Symfony/Component/Serializer/
$ composer install
$ phpunit
