[rules-users] How to continue session, but remove all objects?

[Wolfgang Laun]

In this case, I would just use clear out the working memory:
  for( Person p: ... ){
     insert( p );
     ksession.fireAllRules();
     for( Object object: ksession.getObjects() ){
        ksession.retract( ksession.getFactHandle( object ) );
     }
   }

without recreating another ksession for the next Person (no dispose(), no
newStatefulKnowledgeSession() )

But there's
   ksession.startProcess(this.file);
and anything might happen there, so all bets are off...
