The ResourceFactory Class

The \TYPO3\CMS\Core\Resource\ResourceFactory is the workhorse of the File Abstraction Layer from a coding point of view. It contains a number of utility methods, some of which are described here, some others which appear in the other code samples provided in this chapter.

Getting the Default Storage

Of all available Storages, one may be marked as default. This is the Storage that will be used for any operation whenever no Storage has been explicitly chosen or defined (for example, when not using a combined identifier).

$resourceFactory = \TYPO3\CMS\Core\Resource\ResourceFactory::getInstance();
$storage = $resourceFactory->getDefaultStorage();


This may return null if no default Storage exists.

Getting any Storage

The ResourceFactory should also be used when retrieving any Storage. You should not try to instantiate directly a \TYPO3\CMS\Core\Resource\StorageRepository and call its findByUid() method.

$resourceFactory = \TYPO3\CMS\Core\Resource\ResourceFactory::getInstance();
$storage = $resourceFactory->getStorageObject(3);
