Modelled after Symfony\Component\Cache\Adapter\AbstractAdapter::createSystemCache()

protected CacheInterface createCache(string $class, array $args, bool $useInjector = true)

Creates an object with a PSR-16 interface, usually from a PSR-6 class name

Quick explanation of caching standards:

  • Symfony cache implements the PSR-6 standard
  • Symfony provides adapters which wrap a PSR-6 backend with a PSR-16 interface
  • Silverstripe uses the PSR-16 interface to interact with caches. It does not directly interact with the PSR-6 classes
  • Psr\SimpleCache\CacheInterface is the php interface of the PSR-16 standard. All concrete cache classes Silverstripe code interacts with should implement this interface
