Re: [rules-users] Fusion historical data analysis
Some code snippets that I've used:
import org.drools.time.SessionPseudoClock;
SessionPseudoClock clock;
void advance( Date eventDate ){
long currentTime = clock.getCurrentTime();
long eventTime = eventDate.getTime();
clock.advanceTime( eventTime - currentTime, TimeUnit.MILLISECONDS );
}
KnowledgeSessionConfiguration kSessionConfig =
KnowledgeBaseFactory.newKnowledgeSessionConfiguration();
kSessionConfig.setOption( ClockTypeOption.get("pseudo") );
kSession = kBase.newStatefulKnowledgeSession( kSessionConfig, null );
clock = kSession.getSessionClock();
SomeEvent event = ...;
advance( event.getTimestamp() );
eventStream.insert( event );
kSession.fireAllRules();

Hi,
unfortunately I haven't found any way to set the pseudo clock according to
timestamp (the "session.insert()") in
org.jboss.soa.esb.actions.BusinessRulesProcessor which I am using to fire
the rules from ESB.
I'll try to write my own class to fire the rules, where I can also use
"session.insert()" to synchronize the clock.
the only thing I do not understand is, why it is possible to set the
<property name="ruleClockType" value="PSEUDO" /> in ESB, but I
have no
property to control the session clock...
Thank you for your help.
