RE: [rules-users] Fetching values of an object's attribute set bydifferent rules

Hi Mike, thanks for the reply. Actually for each object I check, depending on how many rules are activated, I'd need so many value holder too. So, each value holder actually contains information about each activated rule (e.g. regarding the temperature and detergent. But thank you for the keyword LIST. I think, instead of using 2 level (i.e. Value Holder and the Match-objects, I could use session.insert(List<ValueHolder>), and for every activated rule, in THEN part I'll create a new ValueHolder, set its values, and add it to the list. But another question to this: How can I insert 2 different kind of lists, and refer to them? I saw that List<MyClass>() can't be used, and only List() is possible when $wash : List() $shirt : List() then $wash.add(new Wash..()) $shirt.add(new Shirt()) Can RE find the correct list to add the objet? Or how should I do this? Again, thanks in advance :) Paul Hi psentosa, I don't fully understand what you require, but won't using a List of WashRuleMatches provide what you need? rule A when $s : Shirt (dirtinessLevel == high) $holder : WashRuleValueHolder() Then System.out.println ("this cloth should be washed in 60 degree water with 1 spoon of detergent") WashRuleMatch m = new WashRuleMatch(); m.setTemperature(60); m.setDetergent(1); m.setShirt($s); $holder.add(m); //insertLogical(m); rule B when $s : Shirt(material == satin) $holder : WashRuleValueHolder() then System.out.println ("this cloth should be washed in 30 degree water with 0,5 spoon of detergent") WashRuleMatch m = new WashRuleMatch(); m.setTemperature(30); m.setDetergent(0.5); m.setShirt($s); $holder.add(m); //insertLogical(m); Do you need only one WashRuleValueHolder for each shirt? [WashRuleValueHolder setup by rules] rule A1.0 when $s : Shirt (dirtinessLevel == high) not WashRuleValueHolder(shirt == $s) Then WashRuleValueHolder wrvh = new WashRuleValueHolder($s); insertLogical(wrvh); rule A1.1 when $s : Shirt (dirtinessLevel == high) $holder : WashRuleValueHolder(shirt == $s) Then System.out.println ("this cloth should be washed in 60 degree water with 1 spoon of detergent") WashRuleMatch m = new WashRuleMatch(); m.setTemperature(60); m.setDetergent(1); m.setShirt($s); $holder.add(m); //insertLogical(m); Etc...
