Thanks Wolfgang, this helps a lot! I must have missed the
getConditionalElements in the API. The analysis of the rule's LHS is
working great and it's RHS is more complex but do-able.
Once again, thanks for the advice,
Pete

Rete has listDefrules and Defrule has getConditionalElements, which
lets you retrieve its constituents, depending on it being a Pattern or
Accumulate; if it is a Group you must recurse down... It's like
walking an AST
RHS is similar. But note that fact modifications are possible in
functions, so if one of these is called on the RHS, you'll have to
investigate in depth.
Expect to have some fun ;-)
Cheers

Dear Jess users.
What I am trying to do is to dynamically list all the defrules together
with their LHS and RHS facts excluding any conditions. Basically what I
mean is that, for example, if there are Person and Car facts on the
rule's
LHS and the rule asserts an Owner fact, deletes the Car fact and modifies
the Person fact. I would like to create a data structure that would, for
each rule, carry it's name and the facts it needs to fire (excluding any
conditions just deftemplate's name) and any deftemplates that appear on
the
rule's RHS. So for the example above, something like:
Rule_1
needs: Person, Car
asserts: Owner
modifies: Person
deletes: Car
I can get a list of all defrules via the listDefrules() method called on
the Rete object but then it gets tricky. The listNodes() method called on
the HasLHS object gives a textual description of the rule's LHS but I
cannot find a method that would simply return name of facts on the LHS.
Some text processing would solve the rule's LHS problem as I can look for
occurrences of :: to find facts. However, the rule's RHS is more
problematic as I cannot find a method that would give me what I want.
I would appreciate your help with this one.
Best regards,
Pete
