Hi Dr Hill,
Thanks a bunch for your help.
I have added the "$" in the Jess file, as shown below
(deftemplate match-muscle-machine
(slot body-part)
(multislot station) );;close
(asserrt (match-muscle-machine (body-part arms-upperfront)
(station N5 N8 N10 C1)) )
(defquery search-relevant-machines "Get the relevant machines"
(declare (variables ?findx))
(match-muscle-machine
(body-part ?findx) (station ?$station)) )
In the Java program
QueryResult result = r.runQueryStar
("search-relevant-machines", new
ValueVector().add("arms-upperfront"));
while (result.next()) {
Value vv = result.get ("station");
From
http://herzberg.ca.sandia.gov/jess/docs/70/api/jess/QueryResult.html
Now Im not sure how best to store the multilslot value. I use jess object
"Value vv" to store it and it works.
But I do not know how to get each of them out so I have tried using
ValueVector
ValueVector vv = result.get ("station");
ValueVector vv = result.getObject ("station");
'cos in the book page 240 on "extending the Jess language" there are ways to
get each value out using
ValueVector.get(1) but the java compiler keeps saying "incompatible types"
when I use the 2 ValueVector statements above.
In short,
How can I get each element out from "Value vv"
Or how can I correctly use ValueVector?
Do people usually use Value or ValueVectors?
thank you so much
rgds
