I am not really sure how that should solve the problem.

why not simply like this:

$objectData['general'] = [
                'index' => $embeddedObject->getIndex(),
                'o_published' => $embeddedObject->getPublished(),
                'o_key' => $embeddedObject->getKey(),
                'o_id' => $embeddedObject->getId(),
                'o_modificationDate' => $embeddedObject->getModificationDate(),
                'o_creationDate' => $embeddedObject->getCreationDate(),
                'o_classId' => $embeddedObject->getClassId(),
                'o_className' => $embeddedObject->getClassName(),
                'o_locked' => $embeddedObject->getLocked(),
                'o_type' => $embeddedObject->getType(),
                'o_parentId' => $embeddedObject->getParentId(),
                'o_userOwner' => $embeddedObject->getUserOwner(),
                'o_userModification' => $embeddedObject->getUserModification()
            ];

Yes sure - much neater!
It worked because the other members were public but I like using the getters instead.
Also, getIndex() returns 0 unless you save and reload the object. But if you close the object and view again it's reverted to 0.
So I added the ++$i.
(Also users prefer index to start with 1 instead of 0)
