Don't try to get the Token - hiding that sort of ugliness is the whole reason
run-query* exists. Use a pattern binding instead:
(defquery my-query
(declare (variables ?n))
?f <- (room (number ?n)))
(bind ?r (run-query* my-query 100))
(while (?r next)
(bind ?fact (?r getObject f))
;; ... now do something with your fact

Thanks Ernest.
In my program, I was using runQuery(arg0, arg1) and storing the result in a
Iterator as shown below. Then I am storing the result in token and from token
to fact.
Iterator sno = engine.runQuery("session-number",new
ValueVector().add(sidValue));
if (sno.hasNext()) {
Token token = (Token) sno.next();
Fact fact = token.fact(1);
Now, I want to use runQueryStar(). But I don't know how to read the Query
Result.
QueryResult sno = engine.runQueryStar("session-number",new
ValueVector().add(sidValue));
if (sno.next()) {
Token token = (Token) sno.????; what function should I use here?
Fact fact = token.fact(1);
