Cache::CacheSizer -- component object for mamanging 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.
