     *                         caller to NULL.  Each time SCAN is invoked, the iterator will be
     *                         updated to a new number, until finally Redis will set the value to
     *                         zero, indicating that the scan is complete.
     *
     * @param string|null $pattern An optional glob-style pattern for matching key names.  If passed as

     *
     * @param int    $count    A hint to redis that tells it how many keys to return in a single
     *                         call to SCAN.  The larger the number, the longer Redis may block
     *                         clients while iterating the key space.

     * @param string $type     An optional argument to specify which key types to scan (e.g.

     * @return array|false     An array of keys, or false if no keys were returned for this

     *                         should instead continue to SCAN until the iterator reference is
