Hi,
I'm doing something like this:
o : MyObject (name == "something")
MyObject (n : name -> (o.getProp("prop") == "val"))
As you can see in the second condition, in order to
use the predicate constraint, I have to bound an
unrelated column. Is there a way to use the predicate
constraint without the column binding?
I know I can use eval, but put everything that is not
a column in eval can get it really cluttered in a
hurry.
So I think it will be helper to be able to filter the
facts based on a non-column, such as:
o : MyObejct (name == "something")
MyObject( -> (o.getProp("prop") == "val")
better yet, without the "->", but I understand if
there has to be something to indicate that it is a
predicate constraint.
Thanks,
Yuesong
