[TYPO3-mvc] Typo3 extbase validating custom or manual objects

[Philipp]

$validatorResolver = $this->objectManager->get('TYPO3\\CMS\\Extbase\\Validation\\ValidatorResolver');
/* @var $validatorResolver \TYPO3\CMS\Extbase\Validation\ValidatorResolver */
$validator = $validatorResolver->getBaseValidatorConjunction(MODELNAME);
/* @var $validator \TYPO3\CMS\Extbase\Validation\Validator\ConjunctionValidator */
$result = $validator->validate($form);

BTW:

you should not use the TYPO3 namespace as your vendorname, this will cause many problems i think.
