Wolfgang,
The requirement for serializable classes even when not using persistence
was a "mistake" made several versions ago and I believed it was fixed. What
version of Drools are you using? If that is trunk, we need to fix it.
Anyway, workaround: for count(), you can simply write "c
When working on incremental change-set processing mode, Knowledge Agent
performs a diff between the original and the modified resources. Modified
resources are compiled, and a visitor pattern is used to loop over knowledge
definitions (such as rules, functions, queries, etc.).
So if rule1 was modif
Hi Tina,
1. In cases like this, either you define an @expires policy that is longer
than your temporal constraints + latency to receive the events, or you run
the engine in cloud mode (disabling the lifecycle management).
2. Yes, correct. As you probably realized, given only the constraint in
Thank you, Edson. :)
I've got two more questions about that for now.
The first one is kind of ... ugly.
I know the stream mode needs a time-ordered stream so that the
processing can be done correctly. In my case it can not really be
predicted at which time an event arrives so that the system/
Hi,
I'm getting a two red highlighted outputs in eclipse if I modify my
rules file during run time. Besides that the modifications seem to work.
What does it mean?
The full output I get when the resource change is detected is listed

This is the way to implement an AgendaFilter so that you can use it with

// ... constructor etc.

I have modified according to your suggestion but still I am getting the

The error message says Stateful*Rule*Session, but I'd say you have a
Stateful*Knowledge*Session ksession.
Do a cast:
org.drools.runtime.rule.StatefulRuleSession sfrs =
(org.drools.runtime.rule.StatefulRuleSession)ksession;
and use this one for firing all rules with an agenda filter.

I think that is the minimum code needed to create a kagent with custom
configuration.
The only line you could remove is:
kbase = kagent.getKnowledgeBase();
Because you are using incremental change-set processing (
drools.agent.newInstance = false), you don't need to obtain a reference to
the new

KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(

Drools also use the 13 temporal operators as "hints", so if you have a
rule:
$a : A()
$b : B( this after[0,3m] $a )
Drools will know that A's must be held in memory for 3 minutes while B's
will expire immediately. Drools will calculate all possible expiration
offsets based on all used tempo
No, not knowingly :-) I'm using the simplest possible setup for
KnowledgeBase, KnowledgeBuilder, StatefulKnowledgeSession.
Why should accumulate/count effect persistence?

In Java, a constructor with package level visibility can be called from some
other class in the same package.
It seems that this is not possible from the RHS of a rule that is in a .DRL
file that has the same "package" declaration as the package of the class
that should be instantiated. An Illegal

As simple as it gets:
rule countHigh
when
$n : Number() from accumulate ( $sgc : StartGoalConn() count( $sgc ) )
then
System.out.println( "plain routes: " + $n );
end
And yet, it fails:

I want to create a KnowledgeBase using stream processing mode, getting

Hi,
I'm thinking about something. Maybe anyone can tell me.
The Stream Processing Mode of Drools Fusion provides automatic lifecycle
