NAME
Cache::CacheFactory::Object - the data stored in a Cache::CacheFactory cache.
DESCRIPTION
Cache::CacheFactory::Object is a subclass extending Cache::Object to allow for per-policy meta-data needed by Cache::CacheFactory's policies.
You will not normally need to use this class for anything.
If you are already using Cache::Object then you'll find that Cache::CacheFactory::Object only extends behaviour, it doesn't alter existing behaviour.
SYNOPSIS
use Cache::CacheFactory::Object;
my $object = Cache::CacheFactory::Object( );
$object->set_key( $key );
$object->set_data( $data );
$object->set_expires_at( $expires_at );
$object->set_created_at( $created_at );
$object->set_policy_metadata( 'expiry', 'time', $metadata );
METHODS
- $object = Cache::CacheFactory::Object->new_from_old( $cache_object, [ $param ] );
-
Construct a new Cache::CacheFactory::Object from a Cache::Object instance, this is done automatically by Cache::CacheFactory methods that provide backwards compat.
$param
is an optional argument that contains additional parameters to pass to$object->initialize()
. - $object->initialize( $key, $data, $param );
-
Initializes the object, this is done seperately from the constructor to make it easier for people to subclass Cache::CacheFactory::Object should they need to.
- $object->set_policy_metadata( $policytype, $policy, $metadata );
-
Set the meta-data for the given
$policytype
and$policy
to the value provided in$metadata
, usually a hashref.See the documentation on Cache::CacheFactory for more information about policy types and policies.
- $metadata = $object->get_policy_metadata( $policytype, $policy );
-
Fetch the meta-data stored by
$policytype
and$policy
.See the documentation on Cache::CacheFactory for more information about policy types and policies.
All other behaviour is inherited from and documented by Cache::Object.
