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.

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.
