[rules-dev] [accumulate] sum is always a double? What if it's only an int?

Hi guys, I finally got around to experimenting with the accumulate support in LocalSearchSolver. Thanks for implementing it :) I use nothing but int's in my calculations, but I get a ClassCastExceptions, as sum() always returns a Double and setSoftConstraintsBroken(int) failes. In a previous benchmarks I 've proven that summing integers in double's instead of int's hurts performance for 10% or more (which is rather big). Is there a sumInteger() available (or do I need to write it)? Or can it be overloaded over sum() in a much cleaner way? rule "ScoreCalculator" when $scoreFact : ScoreFact(); // singleton $total : Integer() from accumulate( Hop($distance : distance ), // distance is an int sum($distance) ); then $scoreFact.setSoftConstraintsBroken($total); end svn is still here, till it's ready for drools: https://taseree.svn.sourceforge.net/svnroot/taseree/trunk -- With kind regards, Geoffrey De Smet
