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



NAME

Cache::CacheSizer -- component object for mamanging 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.


SYNOPSIS

  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.


PROPERTIES

get_max_size
The desired size limit for the cache under control.
