11.1.x vendor/symfony/validator/Mapping/Loader/LoaderChain.php \Symfony\Component\Validator\Mapping\Loader\LoaderChain

Calls multiple {@link LoaderInterface} instances in a chain.

This class accepts multiple instances of LoaderInterface to be passed to the constructor. When {@link loadClassMetadata()} is called, the same method is called in <em>all</em> of these loaders, regardless of whether any of them was successful or not.
