    [Cache::CacheSizer](https://www.chedong.com/phpMan.php/perldoc/Cache%3A%3ACacheSizer/markdown) -- component object for managing the size of caches

      my $sizer = new [Cache::CacheSizer](https://www.chedong.com/phpMan.php/perldoc/Cache%3A%3ACacheSizer/markdown)( $cache, $max_size );

      $sizer->limit_size( $new_size );

        *$max_size*.

### update_access_time
