Either 'module', 'theme', 'config' * or 'content'. * @param array $names * The specific names to check. If $type equals 'module' or 'theme' then it * should be a list of module names or theme names. In the case of 'config' * or 'content' it should be a list of configuration dependency names. * * @return bool * TRUE if the entity has changed as a result of calling the * onDependencyRemoval() method, FALSE if not. */
