[rules-users] accumulate function

Hi everyone, I have this scenario: I have assserted a few elements of the type "SegmentGroup8" into the working memory, this SegmentGroup8 class have inside a list called private List<ControlTotal> cnt; What I need to achieve is to perform a "sum" of one of the fields called c6066 inside the ControlTotal for all the SegmentGroup8 asserted into the WM... I would like to use the accumulate functions but I really dont know how, any help would be appreciated, thanks in advance... the classes code is the following... public class SegmentGroup8 implements Serializable { private List<ControlTotal> cnt; private List<MonetaryAmount> moa; public List<ControlTotal> getCnt() { return cnt; } public void setCnt(List<ControlTotal> cnt) { this.cnt = cnt; } ...... } public class ControlTotal extends Segment implements Serializable { private String c6069; private String c6066; ........ public String getC6069() { return c6069; } public void setC6069(String c6069) { this.c6069 = c6069; } public String getC6066() { return c6066; } public void setC6066(String c6066) { this.c6066 = c6066; } ......... } -- View this message in context: http://drools.46999.n3.nabble.com/accumulate-function-tp3353507p3353507.html Sent from the Drools: User forum mailing list archive at Nabble.com.
