<tt>Hi Edson,<br>
<br>
I am running in stream mode , I used this function <br>
<br>
config.setOption(EventProcessingOption.STREAM);<br>
<br>
to enable it.<br>
<br>
About the clock and time stamping I am not using anything special ,
this is the initiation part of my main :<br>
<br>
<br>
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();<br>
kbuilder.add(ResourceFactory.newClassPathResource("pol.drl"),
ResourceType.DRL);<br>
if ( kbuilder.hasErrors() ) {<br>
System.err.println( kbuilder.getErrors().toString() );<br>
}<br>
KnowledgeBase kbase =
KnowledgeBaseFactory.newKnowledgeBase();<br>
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); <br>
<br>
KnowledgeBaseConfiguration config =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();<br>
config.setOption(EventProcessingOption.STREAM);<br>
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();<br>
WorkingMemoryEntryPoint mainS =
ksession.getWorkingMemoryEntryPoint( "mainS" );<br>
<br>
Thank you,<br><font color="#888888">

Are you timestamping the events or are you using the clock to timestamp

Guys,<br>
<br>
I was working lately with drools fusion, we wanted to know what event<br>
consumption policy was implemented.<br>
We made the following simple rule :<br>
<br>
rule a<br>
<br>
when<br>
$c1 : Event(symbol == 1 , $l1 :load) from entry-point "mainS"<br>
and<br>
$c2 : Event(this after $c1,symbol == 2,$l2 :load) from<br>
entry-point "mainS"<br>
<br>
then<br>
System.out.println("event1 "+$l1+" event2 "+$l2);<br>
<br>
end<br>
<br>
The event class has just symbol : int and load : int , load is used to<br>
differentiate between different events that have the same symbol.<br>
<br>
and then we declared the following events into the stream using the<br>
constructor Event(symbol,load): with mainS being a
WorkingMemoryEntrypoint<br>
<br>
mainS.insert(new Event(1,10.0));<br>
mainS.insert((new Event(1,20.0)));<br>
mainS.insert((new Event(1,30.0)));<br>
mainS.insert(new Event(2,80.0));<br>
mainS.insert(new Event(2,90.0));<br>
<br>
<br>
We have the following output :<br>
<br>
event1 30.0 event2 90.0<br>
event1 20.0 event2 90.0<br>
event1 10.0 event2 90.0<br>
event1 10.0 event2 80.0<br>
<br>
So what is exactly the consumption policy used in DROOLS ? It seems that<br>
is unrestricted for event 90.0 and chronological for event 80 .<br>
<br>
We have tested different situations and order of events and we always<br>
came to the conclusion that for the first $c2 the policy is<br>
chronological and for all the other $c2's it is unrestricted.<br>
<br>
Thank you for you time.<br>
Khalil<br>
