Subject: [rules-users] Math calculations on attributes in WHEN section of rules.
Hello,
what I want to do, is to calculate on object's attributes in WHEN section of
rule. Can I do it?
For example:
class CObj
{
private int k;
private int n;
// setters and getters
}
Now what I want to do is:
rule "r1"
when
p : CObj ( k + n <= 1000)
then
System.out.println("We love Drools :)");
end
Why can't I construct conditions like in Java, or C++ (with calculations in
conditions)? How can I achieve my goal?
Thx,
Tom.
