how to generate function(GuardEvent|TransitionEvent) {...

[tacman]

I'm trying to generate

public function getRow(GuardEvent|TransitionEvent $event): Row

but I can't figure out how to add more than one type. I see setType, but not addType or setTypes()

    $parameter = $method
        ->addParameter('event');
    $parameter
        ->setType(GuardEvent::class)
        ->setType(TransitionEvent::class);

Is there a way to do this? Thx.

Found it! Type::union

        $parameter = $method
            ->addParameter('event');
        $parameter
            ->setType(Type::union(TransitionEvent::class, GuardEvent::class));
