RE: JESS: Accumulate Function - LHS

[Tromm, Martijn]

Yes, that's how you can sweep a lot of data of different type together in one rule. The rule still fires of some types are not present.   Martijn   From: Roger Studner [mailto:[EMAIL PROTECTED] Sent: vrijdag 2 december 2005 13:19 To: jess-users@sandia.gov Subject: JESS: Accumulate Function - LHS   Are there situations or usages of (accumulate) that would actually prevent a rule from firing?     ?c <- (accumulate (bind ?count 0)                        ;; initializer             (bind ?count (+ ?count 1))                    ;; action             ?count             (pattern to look for.. single fact, not even complex)             ) If there are *no matches* to this pattern, should it always fire and have ?c bound to zero?
