[TYPO3-english] initStorageObjects()

[Jan Kornblum]

Dear newsgroups,

can anybody please explain to me what "initStorageObjects()" is needed 
for in a model class?

protected function initStorageObjects() {
	$this->images = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
}

Any extensions i've written don't really need this. The following seems 
to be enough to get the objectstorages work correctly:

/**
 * images
 *
 * @var 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference>
 */
protected $images = NULL;

Am i wrong with this?

Kind regards, Jan
