             * PersistentObject base class that implements getter/setter methods for all mapped fields and associations
             * by overriding __call.
             *
             * This class is a forward compatible implementation of the PersistentObject trait.
             *
             * Limitations:
             *
             * 1. All persistent objects have to be associated with a single ObjectManager, multiple
             *    ObjectManagers are not supported. You can set the ObjectManager with `PersistentObject#setObjectManager()`.
             * 2. Setters and getters only work if a ClassMetadata instance was injected into the PersistentObject.
             *    This is either done on `postLoad` of an object or by accessing the global object manager.
             * 3. There are no hooks for setters/getters. Just implement the method yourself instead of relying on __call().
             * 4. Slower than handcoded implementations: An average of 7 method calls per access to a field and 11 for an association.
             * 5. Only the inverse side associations get autoset on the owning side as well. Setting objects on the owning side
             *    will not set the inverse side associations.
             *
             * @example
             *
             *  PersistentObject::setObjectManager($em);
             *
             *  class Foo extends PersistentObject
             *  {
             *      private $id;
             *  }
             *
             *  $foo = new Foo();
             *  $foo->getId(); // method exists through __call
