deleteByTags ( array | string $tag ) : boolean Delete keys by tags.
deleteOld ( ) : boolean Delete expired cache values.
lockKey ( mixed $key, mixed &$autoUnlockerVariable ) : boolean Get exclusive mutex for key. Key will be still accessible to read and write, but another process can exclude dog-pile effect, if before updating the key he will try to get this mutex.
