    * Overrides Entity::__construct().
+   *
+   * @param array $values
+   *   A multidimensional array holding the entity field values for all the
+   *   available translations. The first key is a field name, the second is a
+   *   language code, the third is a delta, the fourth is a column name. Field
+   *   values for the default entity language (e.g. 'en') should by be keyed
+   *   with LanguageInterface::LANGCODE_DEFAULT. This does not affect actual
+   *   field values, for instance the default language value for the 'langcode'
+   *   field would be 'en' in this case.
+   * @param string $entity_type
+   *   The entity type identifier.
+   * @param string|bool $bundle
+   *   (optional) The entity bundle if the entity type supports it, FALSE
+   *   otherwise. Defaults to FALSE.
+   * @param string[] $translations
+   *   An array of language codes identifying the existing translations for this
+   *   entity.
