Is there a way to disable Doctrine 2 lazy loading?
===

Im using Doctrine 2 ORM in my Zend project and need to serialize my Entities to JSON in several cases.

ATM i use the Querybuilder and join all tables i need. But my serializer causes doctrine to lazy load every associated Entity which results in pretty huge data amounts and provokes recursion.

Now im looking for a way to totally disable Doctrines lazy loading behavior.

My way to select data would be the following:

    $qb= $this->_em->createQueryBuilder()
                ->from("\Project\Entity\Personappointment", 'pa')
                ->select('pa', 't', 'c', 'a', 'aps', 'apt', 'p')
                ->leftjoin('pa.table', 't')
                ->leftjoin('pa.company', 'c')
                ->leftjoin('pa.appointment', 'a')
                ->leftjoin('a.appointmentstatus', 'aps')
                ->leftjoin('a.appointmenttype', 'apt')
                ->leftjoin('a.person','p')

I would like my resultset to only contain the selected tables and associations.

Any help would be greatly appreciated.
