Re: [rules-users] Intersecting two collections in LHS

I have in the working memory all possible sentences that can be presented to the user ( class Sentence() ).**** Each sentence holds a collection (String collection) called descriptor that describe the sentence.**** ** ** Based on various rules I populate a collection called messageFilter which will be used to select the appropriate sentence.**** The proper sentence is one that all its descriptors match the one in the messageFilters**** ** ** What I would like is something of the sort:**** ** ** $sentences: ArrayList() **** *from* *collect* (Sentence(descriptor *contains* messageFilter)**** **** as messageFilter is a collection, this is not a valid code.**** What would be the proper method to implement it.**** ** ** I am using drools 5.1.1 but am willing to upgrade to 5.2 if required.**** ** ** Thanks,**** Hezi**** ** ** _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
