Re: [rules-users] get inserted facts
Without changing the rules: you might also use a WorkingMemoryEventListener to collect the inserted new Fact objects. A StatefulKnowledgeSession provides the method getObjects(), with or without a filter, so you might consider using that. -W 2011/7/6 Nathan Bell nathan.b...@pharmacyonesource.com Without knowing your use cases, or what you intended to do with the facts once you retrieve them, I’d suggest that you could simply add them to a global list and examine the list contents after rule processing. For example: ** ** import java.util.List; ** ** global List results; ** ** rule IWantToTrackMyConsequenceFacts when Type1(filter1 =1) then Fact someFact = new Fact(); insert(someFact); results.add(someFact); end ** ** ** ** Prior to executing the rule(s) you will have to set that global variable to a valid list object with something like this: ** ** knowledgeSession.setGlobal(“results”, new ArrayList()); ** ** ** ** ** ** *From:* rules-users-boun...@lists.jboss.org [mailto: rules-users-boun...@lists.jboss.org] *On Behalf Of *Ruault Gaetan *Sent:* Tuesday, July 05, 2011 5:13 PM *To:* Rules Users List *Subject:* [rules-users] get inserted facts ** ** Hi, ** ** I use drools in stateless Session like this : ** ** session.execute( my_facts_list) ; ** ** and i have many rules like this ** ** when Type1(filter1 =1) Then Insert( new Fact()) ; ** ** ** ** Could you explain how it’s possible to retrieve my new facts in java code ? ** ** ** ** Thanks. ** ** Gaetan ** ** ** ** ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] get inserted facts
Option 1 is to just use a stateful session - from my understanding there is pretty much no difference in terms of overhead. The other option is to insert a 'ResultsAccumulator' object containing a resultList. I If you don't need to reason over your new Facts than rather than inserting them just add them to the result list. Alternatively have a low salience rule which will only run at the end which accumulates up all the facts and adds them to the result list (either with accumulate or one by one).
