Class

ThemeRegistry

Builds the run-time theme registry.

Code

public function offsetExists($offset) {

  // Since the theme registry allows for theme hooks to be requested that
  // are not registered, just check the existence of the key in the registry.
  // Use array_key_exists() here since a NULL value indicates that the theme
  // hook exists but has not yet been requested.
  return isset($this->storage[$offset]) || array_key_exists($offset, $this->storage);
