RE: JESS: calling a method on a matched shadow fact
Hi, In the LHS of a rule, could I bind to a variable a object that is returned from a method called on a matched fact ? (rule x (theShadowfact ?o) (... ?o getXYZ ... ) The purpose of doing this is to have a variable on which to do some tests without having to call getXYZ for each one of them.

Re: JESS: calling a method on a matched shadow fact
One way to do this would be to use progn in a test CE: (defrule x (theShadowFact (OBJECT ?o)) (test (progn (bind ?xyz (?o getXYZ)) (and ( ?xyz 10) ( ?xyz 100 = ... progn executes all the function calls inside it, then returns the value of the last one.

JESS: calling a method on a matched shadow fact
Hi,
Let's say I have something like :
(defclass xyz x.y.com.XYZ)
(defrule x
?x-(xyz)
=
(...)
In the RHS, I would like to call a method that is not a bean get/set on the
matched 'xyz', what would be the proper way? (If possible, this method would
take a string as argument)
Thanks,
JFL

Only simple expressions as described in the manual are handled in this
release. Parenthesized expressions are not implemented -- yet.

But his expression cannot be parsed by Jess.
