Class

LanguageFormatter

Plugin implementation of the 'language' formatter.

Namespace

Drupal\Core\Field\Plugin\Field\FieldFormatter

Code

protected function viewValue(FieldItemInterface $item) {

  // either displayed in its configured form (loaded directly from config
  // storage by LanguageManager::getLanguages()) or in its native language
  // name. That only depends on formatter settings and no language condition.
  $languages = $this->getSetting('native_language') ? $this->languageManager

    ->getLanguages(LanguageInterface::STATE_ALL);
  // \Drupal\Core\Language\LanguageInterface::LANGCODE_NOT_SPECIFIED
  // and \Drupal\Core\Language\LanguageInterface::LANGCODE_NOT_APPLICABLE are
  // not returned from the language manager above.
