Code

protected function cacheGet($ids, $conditions = array()) {
  $entities = array();
  // Load any available entities from the internal cache.
  if (!empty($this->entityCache)) {
    if ($ids) {
      $entities += array_intersect_key($this->entityCache, array_flip($ids));
    }
    // If loading entities only by conditions, fetch all available entities
    // from the cache. Entities which don't match are removed later.
    elseif ($conditions) {
      $entities = $this->entityCache;
    }
  }

  // Exclude any entities loaded from cache if they don't match $conditions.
  // This ensures the same behavior whether loading from memory or database.
