Cache::SizeAwareCache(User Contributed Perl DocumentatCache::SizeAwareCache(3)

NAME
       Cache::SizeAwareCache --	extends	the Cache interface.

DESCRIPTION
       The SizeAwareCache interface is implemented by classes that support all
       of the Cache::Cache interface in	addition to the	limit_size and
       max_size	features of a size aware cache.

       The default cache size limiting algorithm works by removing cache
       objects in the following	order until the	desired	limit is reached:

	 1) objects that have expired
	 2) objects that are least recently accessed
	 3) objects that expire	next

SYNOPSIS
	 use Cache::SizeAwareCache;
	 use vars qw( @ISA );

	 @ISA =	qw( Cache::SizeAwareCache );

CONSTANTS
       Please see Cache::Cache for standard constants

       $NO_MAX_SIZE
	   The cache has no size restrictions

METHODS
       Please see Cache::Cache for the standard	methods

       limit_size( $new_size )
	   Attempt to resize the cache such that the total disk	usage is under
	   the $new_size parameter.  $new_size represents t size (in bytes)
	   that	the cache should be limited to.	 Note that this	is only	a one
	   time	adjustment.  To	maintain the cache size, consider using	the
	   max_size option, although it	is considered very expensive, and can
	   often be better achieved by periodically calling limit_size.

OPTIONS
       Please see Cache::Cache for the standard	options

       max_size
	   Sets	the max_size property (size in bytes), which is	described in
	   detail below.  Defaults to $NO_MAX_SIZE.

PROPERTIES
       Please see Cache::Cache for standard properties

       (get|set)_max_size
	   If this property is set, then the cache will	try not	to exceed the
	   max size value (in bytes) specified.	 NOTE: This causes the size of
	   the cache to	be checked on every set, and can be considered *very*
	   expensive in	some implementations.  A good alternative approach is
	   leave max_size as $NO_MAX_SIZE and to periodically limit the	size
	   of the cache	by calling the limit_size( $size ) method.
