Hi, i'm migrating from phalcon 2.0 to 4.0 and I don't know how can I upgrade this library.

protected function addResources()
    {
        if (!(array)$this->resources->get('resource')) {
            throw new Exception('Key "resource" must exist and must be traversable.');
        }
        foreach ($this->resources->resource as $name => $resource) {

            $actions = (array)$resource->get('actions');
            if (!$actions)   $actions = NULL;

            $this->acl->addResource($this->makeResource($name, $resource->description), $actions);
        }
        return $this;
    }

( ! ) Fatal error: Uncaught Error: Call to undefined method Phalcon\Acl\Adapter\Memory::addResource() in /var/www/html/src/Common/Library/Memory.php on line 91 ( ! ) Error: Call to undefined method Phalcon\Acl\Adapter\Memory::addResource() in /var/www/html/src/Common/Library/Memory.php on line 91 Call Stack
