My structure is composed of 2 classes (Node, Link) class Node { List <Link> out; List <Link> in; } class Link { Source node; Target node; }
they are inserted as facts in working memory. I have to write a rule that will unite for each node joins the links that have the same destination, and if there is then the inverse must also join the latter. eg. A - link1 -> B A - link2 -> B A - link3 -> C C - link4 -> D B - link5 -> A result A - link1 + link2 +link5 -> B A - link3 -> C C - link4 -> D Can anyone help me? -- View this message in context: http://drools.46999.n3.nabble.com/Help-write-rule-drools-tp4029841.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
