Hi All,
I have aother question on drools.
There can le level1 to level6 present in a rule and we need to pick always
the highest level rule which satisfied list price and discount comdition.
Following code is giving me expected results but do we have any better way
to implement the same. Can I avoid last 2 iternations and combine it to
first one iteration.
RoutingRule.java
----------------
private String level1 = "";
private String level2 = "";
private String level3 = "";
private String level4 = "";
private String level5 = "";
private String level6 = "";
private String serviceSalesPath = "";
private String productSalesPath = "";
private String nonStdTerm = "";
private String currency = "";
private double listPriceFrom = Double.MAX_VALUE ;
private double listPriceTo = Double.MAX_VALUE ;
private double discountPriceFrom = 100;
private double discountPriceTo = 100 ;
private double nodeOfRule =0;
Rule
-----
$selectedTSSRulesWithOutHier : ArrayList()
from collect ($routingRule : RoutingRule(currency == $curr
&& (
listPriceFrom <= $tssListPrice && listPriceTo > $tssListPrice
&& discountPriceFrom <= $tssDisc && discountPriceTo > $tssDisc
&&
nonStdTerm =="TSS" )
)
from $tssRoutingRuleList)
$lowestNodeTSS : Double(intValue > 0)
from accumulate ( RoutingRule($nodeOfRule : nodeOfRule)
from $selectedTSSRulesWithOutHier, max($nodeOfRule))
$lowestNodeTSSRule : ArrayList()
from collect( $ruleObj : RoutingRule( eval(nodeOfRule == $lowestNodeTSS) )
from $selectedTSSRulesWithOutHier )
Many thanks in advance,
Gaurav

Hi Guarav,
I might not be understanding your problem, but think you might be making the
problem more complicated than it needs to be. Could you try something like
the following:
$ruleToChoose : RoutingRule (listPriceFrom <= $tssListPrice, listPriceTo >
$tssListPrice
&& discountPriceFrom <= $tssDisc,
discountPriceTo > $tssDisc,
nonStdTerm =="TSS", $nodeOfRule :
nodeOfRule) from $tssRoutingRuleList
not RoutingRule (listPriceFrom <= $tssListPrice, listPriceTo > $tssListPrice
, discountPriceFrom <= $tssDisc,
discountPriceTo > $tssDisc,
nonStdTerm =="TSS", nodeOfRule >
$nodeOfRule) from $tssRoutingRuleList
Note that this logic states:
Assign to $ruleToChoose a RoutingRule that satisfies our conditions when
there is no other RoutingRule that also satisfies our conditions but has a
higher nodeOfRule value.
Also note that I removed you "&&" operators and replaced them with
","
(comma).
Let me know if I have misunderstood your problem.
Hope it helps!
Enda

Hi Enda,
Thanks for your suggestion.
Problem Statement: I want to pick up rule which satisfies below conditions
and has highest node.
$tssRoutingRuleList can contain more than 2000 rules and I was trying to
avoid iteration over with the same list again. In your suggestion it will
pick up one rule and then it will again search for the same in
$tssRoutingRuleList whether it has another rule which is at higher level or
not.
Here is what I was trying to achieve:-
In my scenario I was picking up all the rules which qualifies the below
mentioned conditions. Selected rules will not be more than 10 and then I am
iterating over that 10 rules list to find the rules which has higest node.
Please let me know if I am not the right way or not.
I am a beginner of drools so not aware of the following. Could you please
clarify the +ve side of the this.
Also note that I removed you "&&" operators and replaced them with
","
(comma).
Thanks,
Gaurav

Try using dynamic salience, it allows you to specify an MVEL expression
that returns an integer value for the salience. The expression can use
any bound declaration at the point of activation.
