Ok let me give you more context:
def process_relation(relation)
return something else when relation.is_none?
# do some more processing here since we know relation will return
results and then return processed result
end
The problem is if I need to figure out whether a relation
But the thing is if you are passed a relation as method argument, how you
check whether its a none relation ? It's similar to checking nil on a
method argument

That's the only way right now.
Although, seems wrong to me check if a relation is a null relation, that's
the point of null objects, you should not know that's a null object at all
(may be necessary in your case but seems wrong to me).
What you can do is something like `relation.empty?' which

I agree with Gabriel Sobrinho. This check goes against the point of having
a NullRelation at all. Maybe you can provide more context about your
use-case and why you need that check.
