Namespace

Code

function __construct($cid, CacheBackendInterface $cache, LockBackendInterface $lock, $tags = array(), $modules_loaded = FALSE) {
  $this->cid = $cid;
  $this->cache = $cache;
  $this->lock = $lock;
  $this->tags = $tags;
  $this->persistable = $modules_loaded && \Drupal::hasRequest() && \Drupal::request()->isMethod('GET');

  // @todo: Implement lazyload.
  $this->cacheLoaded = TRUE;

  if ($this->persistable && $cached = $this->cache->get($this->cid)) {
    $this->storage = $cached->data;
  }
  else {
    // If there is no runtime cache stored, fetch the full theme registry,
    // but then initialize each value to NULL. This allows offsetExists()
    // to function correctly on non-registered theme hooks without triggering
    // a call to resolveCacheMiss().
    $this->storage = $this->initializeRegistry();
    foreach (array_keys($this->storage) as $key) {
      $this->persist($key);
    }
    // RegistryTest::testRaceCondition() ensures that the cache entry is
    // written on the initial construction of the theme registry.
    $this->updateCache();
  }
