[rules-users] get inserted facts

[Nathan Bell]

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());

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
