CacheableNavigationService::callback_spl
This callback is run before PHP invokes its class-level unserialize() function and for reasons beyond the realms of human understanding (B.R.O.H.A), the module is unable to do anything without this static unless you want {@link Zend_Cache_Frontend_File} to be returned as an instance of _PHP_Incomplete_Class_ instead.
Signature
public function callback_spl()
Returns
- void
