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
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
