Re: [rules-users] Separate selectable drl files in drools kbase.. Or agenda groups

Hi Wolfgang, Thanks for the suggestions. I have a few questions, does changing the focus on the RHS work like : kcontext.getKnowledgeRuntime().getAgenda().getAgendaGroup( "B to D" ).setFocus();

Do I need to import kcontext ? or is it implicitly in scope already ?

> a low salience rule would set > the AG for the Spartan group and so on. As I understand it, salience helps the engine decide "which" rule to run, when one or more matches, but does that mean identical factors ,, or just any that are applicable ?

Will the below example work ? Will "b only" fire last like I want it to ?

class Foo { boolean a; boolean b; } (object inserted has a and b == true), Agenda-group Focus is set to "Intialisation" --- rule "a only" agenda-group "Initialisation" salience 10 when Foo (a == true) then … end rule "a and b" agenda-group "Initialisation" salience 5 when Foo (a == true, b == true) then … end rule "b only" agenda-group "Initialisation" salience 1 when Foo (b == true) then kcontext.getKnowledgeRuntime().getAgenda().getAgendaGroup( "WorkerGroup" ).setFocus(); end Many thanks Ramon Ramon Buckland ramon(a)thebuckland.com On 5 Jun 2013, at 06:47, Wolfgang Laun <wolfgang.laun(a)gmail.com&gt; wrote: > You can change the focus on the RHS of a rule as well, using the API. > Starting in the default agenda group, a low salience rule would set > the AG for the Spartan group and so on. > > Notice that any attribute can be set in front of or in between rules to > become effective in successive rules.
