Note that in the book example, the variable ?name is bound to a slot
in the CE, but in your example, you don't do that with your variable ?
domain. You can just add it to the pattern:
(TicketQV (duration ?s&:(< ?s 3)) (domain ?domain))

Hello , i am trying to use accumulate CE element
My jess version Jess71p2
The example ( accumulate from pdf 6.15) works nicely …
----------------------------------------------------------------------
-------
(deftemplate employee (slot salary) (slot name))
(defrule count-highly-paid-employees2
?c <- (accumulate (bind ?list (new java.util.ArrayList)) ;;
initializer
(?list add ?name) ;; action
?list ;; result
(employee (name ?name) (salary ?s&:(< ?s 100000)))) ;; CE
=>
(printout t (?c toString) crlf)
----------------------------------------------------------------------
------
But trying to adapt to my own use case ( with java classes) , i
have problem
----------------------------------------------------------------------
------
(import emb.myown.model.*)
(deftemplate TicketQV (declare (from-class TicketQV)))
;; TicketQV has domain and duration slots from java code
(defrule Accumulate-tickets
"XXX"
?infos <- (accumulate (bind ?list (new java.util.ArrayList)) ;;
initializer
(?list add ?domain) ;; action
?list ;; result
(TicketQV (duration ?s&:(< ?s 3)))) ;; CE
=>
(printout t (?infos toString) " Accumulated tickets." crlf))
------------------------------------------
test:
