Hello,

It seems that is not possible to make rules with operators like "collect"
that affects the rule to a set of objects.

It is possible to simulate that behaviour of collect in some form?

I need to fire rules that have conditions over a set of objects (of same
type) but i don't know how to group conditions over multiple same objects.


For example :

rule CarsStopped

when
    $c:Car (stop = true)  // here i need a collect, i want multiple objects
in one rule that
then
  print("The list of cars stoped is:$c);

end


It seems that "collect" doesnt exist. It is possible to simulate that ?

Actually i ame using JRules and want to use drools too, but i am having
dificulties to do what i can do with JRules.

Thank you very much for your responses.
