Details
__construct(string $identifier, BackendInterface $backend)
Constructs the cache
void
initializeObject()
Initializes this frontend
The backend is connected with this frontend in initializeObject(), not in __construct(), because the Cache Factory needs an opportunity to register the cache before the backend's setCache() method is called. See CacheFactory::create() for details. A backend (for example the SimpleFileBackend) may rely on the cache already being registered at the CacheManager when its setCache() method is called.
