Good day,
Im using java to load the "cardio.clp" file then java ex-commend a string to
create ththe following fact in jess.
(program-cardio
(ident cardio-low)
(cond-inte 40) (cond-dura 6)
(impr-inte 70) (impr-dura 20)
(main-inte 70) (main-dura 1)))
I read in the "Jess in action" book (p311) there is a "findFactByFact()"
method, but I dont know how to use it. Can you please help me? How do I get
the (program-cardio) fact out of Jess? Is ValueVector the correct format to
store the fact? Or should I use vectors?
And is there a way to auto format the retrieved fact in a array for easy
using? Or something similar? Like-
String [] [] cardio_program = {
("ident", "cardio-low"),
("cond-inte", "40"), ("cond-dura", "6"),
("impr-inte", "70"), ("impr-dura", "20"),
("main-inte", "70"), ("main-dura", "1") }
The "cond-inte 40" stands for "conditioning intensity at 40%" which Im
suppose to use it for some java caculation.
Thank you very much for your help
