[TYPO3-english] Getting sys_file_reference records by uid

[Jan Kornblum]

Hi group, again,

this seems to work:

$uid = $this->configurationManager->getContentObject()->data['uid'];
$fileRepository = 
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Resource\\FileRepository');
$fileObjects = $fileRepository->findByRelation('tt_content', 'image', 
$uid);

It fetches all FileReference objects for the current content element.

But what i don't understand: These objects are of type 
TYPO3\CMS\Core\Resource\FileReference. When i debug any models of an 
extension which contains FAL properties, these objects are of type 
TYPO3\CMS\Extbase\Domain\Model\FileReference.

So a) what is the difference between both and b) how can i get my 
origin approach to return TYPO3\CMS\Extbase\Domain\Model\FileReference 
objects instead of TYPO3\CMS\Core\Resource\FileReference objects?

I'm confused ;)

Kind regards, Jan
