# Cache::CacheSizer(3pm)

## 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.
