#013218: Add lazy initialization to PersistentObject component

Could you please offer any insights on how this could work, and when/how it is useful?

If you don't want to init the po session in general and also don't want to track where you use it (and then manually instatiate it). With lazy initialization I can just use it in a gateway class and don't have to care about the PO session.

Before throwing the exception for an unknown session in ezcPersistentSessionInstance::get() a check for the callback should be performed.

Together with the lazy initialization of the Db component this would be possible:

class customLazyPersistentSessionConfiguration implements ezcBaseConfigurationInitializer
{

public static function configureObject( $instance )
{
$session = new ezcPersistentSession(
ezcDbInstance::get(),
new ezcPersistentCodeManager( '../persistent' )
);
return $session;
}
}
