thx for your help..<br>
so i have to implement an accumulate function which counts based on matching<br>
ids, the reference will be set in the init method and the accumulate methods<br>
then checks whether its the same or not , ok<br>
<br></blockquote><div><br>The init method should just do<br> Map<ID,Integer> id2count = new ...<br>or equivalent. The result - a Collection - could be the Entry Set of the map.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
what is this "reverse" method for ? (when does drools has to reverse this ?<br>
, do i have to reverse the count or also the check ?)<br></blockquote><div><br>It's called for a matching element being retracted. If you count, it'll subtract one.<br><br>If you need to know, and react to, all individual excess occurrences, the collection of counters should be analyzed after the accumulate.<br>
