Thanks for your reply.
Also let me know about facts which are loaded into working memory (Keeping
in mind that I'm not calling session.dispose()).
Where should I define their expiry time or how should I retract them after 5
minutes?
You declare the class to represent an event and set the expiry time.
import ...MyEventType
declare MyEventType
@role( event )
@expires( 5m )
end
Or you could catch them with a one-shot timer rule where other actions
besides retract would be possible.
rule "kill after 5m"
timer(int: 5m)
when
$f: SomeType()
then
// other actions?!
retract( $f );
end
Using a suitable interface or supertype may reduce the number of
required rules.
