Hi,
Just to let you know that I solved my own problem.
I had not realized that with a query like
(defquery q
(declare (variables ?foo))
?x <- (t (foo ?foo))
)
I can access variable ?x and turn it into a fact object (although I have
done it before). I then did something like:
QueryResult qr = jess.runQueryStar("q", new ValueVector().add(1));
qr.next();
qr.get("x").factValue(engine.getGlobalContext()).getDeftemplate().getBaseName()
Is there an easier way to do it?
