Cache::CacheSizer -- component object for managing the size of caches
The CacheSizer class is used internally in SizeAware caches such as
SizeAwareFileCache to encapsulate the logic of limiting cache size.
use Cache::CacheSizer;
my $sizer = new Cache::CacheSizer( $cache, $max_size );
$sizer->limit_size( $new_size );
- new( $cache, $max_size )
- Construct a new Cache::CacheSizer object for the cache
$cache with a maximum size of
$max_size .
- update_access_time( $key )
- Inform the cache that the object specified by $key
has been accessed.
- limit_size( $new_size )
- Use the sizing algorithms to get the cache down under
$new_size if possible.
- get_max_size
- The desired size limit for the cache under control.
