NAME

Cache::CacheSizer -- component object for managing the size of caches

DESCRIPTION

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 );

METHODS

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.
