Typo3/Extbase: LazyObjectStorage - access $fieldValue or $parentObject

Question

I need to make some improvements to a Typo3-extension and have a question regarding the ObjectStorage.

TYPO3\CMS\Extbase\Persistence\Generic\LazyObjectStorage has the properties $parentObject and $fieldValue. Both are protected, no getter is defined in the class.

Is there any way to access the properties?

What I am trying to achieve:

class Topic extends AbstractEntity implements ... {
    /**
     * All users who have read this topic.
     *
     * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Mittwald\Typo3Forum\Domain\Model\User\FrontendUser>
     * @lazy
     */
    protected $readers;

    public function __construct($subject = '') {
        // other stuff
        $this->readers = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
    }

    // more stuff
}

The corresponding column in the database holds an integer value, the property in the Model class is the ObjectStorage. I am not interested in the object, but in the integer value.

After initializing the ObjectStorage and populating, the properties are existing, but not accessible.

What to do? Thanks for input.

LazyObjectStorage extends \TYPO3\CMS\Extbase\Persistence\ObjectStorage and this class implements \Countable, so you can simply use count($this->readers) to get the size.
