Alzabo::ObjectCache::Store::Memory - Cache objects in memory
use Alzabo::ObjectCache( store => 'Alzabo::ObjectCache::Store::Memory',
sync => 'Alzabo::ObjectCache::Sync::Null' );
This class simply stores cached objects in memory. This means that a given object should never have to be created twice.
This module has no upper limit on how many objects it will store. If you are operating in a persistent environment such as mod_perl, these will have a tendency to eat up memory over time.
In order to prevent processes from growing without stop, it is
recommended that you call the clear method at the entry
point(s) for your persistent application. This will flush the cache
completely.
Note that pretty much all the methods that take an object as an
argument will silently do nothing if the object is not already in the
cache. The obvious exception is the
store_object method.
A new Alzabo::ObjectCache::Store::Memory object.
The specified object if it is in the cache. Otherwise it returns undef.
Stores an object in the cache. This will not overwrite an existing
object in the cache. To do that you must first call the
delete_from_cache method.
This method allows you to remove an object from the cache. This does
not register the object as deleted. It is provided solely so that you
can call store_object
after calling this method and have
store_object actually
store the new object.
Call this method to completely clear the cache.
