Add a max depth option during the normalization process. Especially useful when normalizing trees.

Usage:

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,
                        ),
                ),
        );
*/

Metadata support
@MaxDepth(2) annotation and loader
XML loader
YAML loader
Delegate recursive normalization at the end of the process
Use constants with Late Static Binding in the abstract class instead of raw strings
Move common logic to the abstract class

Isn't that a BC break?

Good catch, needs a new interface...

By the way, I think than introducing such interfaces was a (my) mistake. Serializer Metadata are value objects. Nobody will (nor should) implement these interfaces. Composition is better for "extending" metadata.

What do you think about marking them as @internal (and even deprecated) @symfony/deciders?

#17114 merged

GuilhemN · 2015-12-22T21:11:54Z

What do you think about using the reference operator &$data to avoid useless copy of the array?

You can also add an array type hint.

I prefer to avoid references when possible (http://schlueters.de/blog/archives/125-do-not-use-php-references.html).

Typehint added.

Ok makes sense.

GuilhemN · 2015-12-22T21:23:29Z

👍 to merge this.
Just needs to take a decision about the interface.

GuilhemN · 2015-12-22T22:02:37Z

Sounds good to me

ping @symfony/deciders

Would be nice to merge soon to be able to work on #16143 without creating conflicts.

xabbuh · 2015-12-30T10:48:22Z

What about also checking that the value is greater than zero?

It has been forgotten during a refactoring. It has always been unused, is not covered by our test suite and has never been documented. Technically it's a BC break (because this is a protected method), but I think that it's better to remove it has it has never be intended to be used, it's just a miss. An alternative is to deprecate it and remove it in v4. Commits ------- fea18aa [Serializer] Remove AbstractObjectNormalizer::isAttributeToNormalize
