JESS: Listening to added facts
Hello, one can catch the asserted and retracted facts in the knoledgebase by setting the event mask to JessEvent.FACT. How about catching only asserted facts(not retracted) or is there anyway to discriminate between them? thanks, -- Levent Kent
Re: JESS: Listening to added facts
When an event comes, check the type. WHen a fact is asserted, you'll get the constant JessEvent.FACT; if it's being retracted, the type is JessEvent.FACT + JessEvent.REMOVED .
