Why ObjectManager instead of EntityManagerInterface?

[aivchen]

ReferenceRepository depends on ObjectManager interface:

data-fixtures/src/ReferenceRepository.php

Line 67 in 4892c74

public function __construct(ObjectManager $manager)

But futher in code getUnitOfWork method is called:

data-fixtures/src/ReferenceRepository.php

Line 127 in 4892c74

$uow = $this->manager->getUnitOfWork();

\Doctrine\Persistence\ObjectManager interface doesn't contain this method. But \Doctrine\ORM\EntityManagerInterface contains.

Could you tell me, why there is a dependency on ObjectManager instead of EntityManagerInterface?

Thanks!

Because doctrine/data-fixtures is not specific to the ORM. The code supports multiple Doctrine O*M projects.

But it is true that the ReferenceRepository does not work with any implementation of Doctrine\Persistence\ObjectManager, only with implementations in those projects.

Ok, got it, thanks.

Then is my doc-annotation correct in this case?

    /**
     * Currently used object manager
     *
     * @var \Doctrine\ORM\EntityManagerInterface|\Doctrine\ODM\MongoDB\DocumentManager|\Doctrine\ODM\PHPCR\DocumentManagerInterface
     */
    private $manager;

    public function __construct(ObjectManager $manager)
    {
        $this->manager = $manager;
    }
