# Cache::CacheSizer - phpMan

## 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.
