[rules-users] Qualifing objects on LHS

[kissro at lidp.com]

Hello,

I have the following rules with the corresponding code in the LHS of
each in a single .drl file.  These were not written by me but by someone
just as new to drools as I am.  At the moment I'm not concerned with the
RHS of the rule.

rule "L_Quest_Q1_Add"
        salience 20
        when
            not FormResponse(questionNumber == "Q1")
            l_Quest : L_Quest(questionNumber =="Q1")

rule "L_Quest_Q3_Add"
        salience 20
        when
            not FormResponse(questionNumber == "Q3")
            l_Quest : L_Quest(questionNumber =="Q3")

rule "L_Quest_Q2_Add"
        salience 10
        when
            formResponse1 : FormResponse(questionNumber == "Q1",
                                         responseData == "Yes")
            not FormResponse(questionNumber == "Q2")
            l_Quest : L_Quest(questionNumber =="Q2")

rule "L_Quest_Q4_Add"
        salience 10
        when
            formResponse3 : FormResponse(questionNumber == "Q3",
                                         responseData == "Yes")
            not formResponse4 : FormResponse(questionNumber == "Q4")
            l_Quest : L_Quest(questionNumber =="Q4")

I want to rewrite these rules in a .dsl file making them as generic as
possible.  Something like

when question {q} is not answered=not FormResponse(questionNumber == {q}

My question is regarding how to reference the 'formResponse' object.
For rule Q2_Add, do I really need to create 'formResponse1' and for rule
Q4_Add, do I have to create 'formResponse3' and 'formResponse4'?   I
don't really want to have specific rules in my .dsl file like

when question 1 is answered=FormResponse1(questionNumber == 1, etc.
when question 3 is answered=FormResponse3(questionNumber == 3, etc.
when question 4 is not answered=not FormResponse4(questionNumber == 4)

Since I may have lots of questions, I don't want to have to have the
numbers hard-coded in the .dsl syntax if I don't have to.  That's why
I'm wanting to know if I have to qualify 'FormResponse' so the rule
engine knows which 'FormResponse' I mean.

Thanks,
Rod
