[rules-users] Drools fusion logic

Sunday, 3 November 2013

Hi all,

I am using Drools Fusion in stream mode.
Let's assume I have a very simple rule:

rule "Simple"

enabled true

dialect "java"

no-loop

when

    $myEvent : MyEvent()

then

   System.out.println($myEvent.toString());

end

1.       When will the rule be fired? If there is a "MyEvent" in working memory?
Or only if a new "MyEvent" was inserted since last activation?

2.       Will the rule be activated for each compatible (as answered in q1)
"MyEvent"? or for just one arbitrary "MyEvent"?

3.       What if my LHS was  "$myEvent : MyEvent() over window:time(60s)"? Were
the answers for q2 and q3 different?

Thanks.
