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.
