JESS: Getting asserted fact from Activation object in JessListener

[Dwight Hare]

In my JessListener I looked at all of the facts from the Token gotten from the Activation. I see all the facts matched in the patterns, but I want access to the fact asserted in the action clause.

 

So if my rule is:

 

(defrule SIRS

            ?ab <- (logical (AbnormalTemperature))

            ?ev <- (logical (ElevatedHeartRate {patientId == ab.patientId}))

            ?p <- (Patient {patientId == ab.patientId})

            =>

            (assert (SIRS (patientId ?p.patientId)))

)

 

Then in the listener I see the facts matched in the pattern but I don’t see the SIRS fact asserted in the action part. Can I access this asserted fact somehow?

 

Thanks

Dwight

You can listen for JessEvent.DEFRULE_FIRED events. Any successive JessEvent.FACT events (up to certain other events) are assert results executed on the RHS of that rule.
