Scaffold::Cache - The base class for Caching in Scaffold
my $server = Scaffold::Server->new( cache => Scaffold::Cache::FastMmap->new( namespace => 'scaffold', ), );
Scaffold provides two caching engines, they are Scaffold::Cache::FastMmap and Scaffold::Cache::Memcached. This module defines the stanadard api that the engines need to implement.
Scaffold::Cache::Manager is used to maintain the caching subsystem. It is implemented as a plugin.
Since the cache can be shared between multiple processes, a "name space" is defined to help differate between those processes cache usage. By default this is "scaffold". It can be changed at any time with the namespace() method or upon initialization of the engine.
When Scaffold initializes itself, it looks for the "cache" config stanzia. If one is defined than that is used for the caching engine, otherwise it will use Scaffold::Cache::FastMmap.
This method will retrieve the "value" associated with "key".
$value = $self->scaffold->cache->get('junk');
This method will store the "value" associated with "key".
$self->scaffold->cache->set('junk', $value);
This method will delete the "key" from the caching system.
$self->scaffold->cache->delete('junk');
This method will update the "value" associated with "key". Most of the caching systems do this in a "atomic" fashion.
$self->scaffold->cache->update('junk', $newvalue);
This method will clear all items from the cache. Use with care.
$self->scaffold->cache->clear();
This method will purge expired items out of the cache.
$self->scaffold->cache->purge();
This method will get/set the current namespace for cache operations.
$namespace = $self->scaffold->cache->namespace; $self->scaffold->cache->namespace($namespace);
