Get file identifier from fileObject in TYPO3 API

i am learning how to deal with files and file-refences in TYPO3. This line get me the correct file objects: 

$fileObject = $fileRepository->findByRelation('fe_users', 'image', $uidOfUser);

But how do i get the file identifier from this object? (In fluid it would be no problem, but i can't use fluid here).

Thanks?

First of all FileRepository::findByRelation() returns a list of file reference objects, not a single file reference:

$fileReferences = $fileRepository->findByRelation('fe_users', 'image', $uidOfUser);

Then you can iterate the file references or pick the first to retrieve the identifier:

if (!empty($fileReferences[0])) {
    $fileIdentifier = $fileReferences[0]->getIdentifier();
}

Notice that you can also get no file references at all, thus an empty list. So make sure the reference you try to access actually exists.
