[rules-users] comparing an intersection of sets..

Hi, I have a situation where i need to evaluate a condition where the intersection of 2 sets should atleast have one element in it. I am using drools template to create the DRL and have a set B (item1,item2, item3, item4). Now, at runtime i have a setA (item2, item5). the intersection of the sets will have item2 and such should evaluate to true. I am currently using evaluate to do a custom function but just wanted to check if there was a way to do something like this by utilizing one of the existing keywords available. Any insight will be very appreciated. thanks for your time. -ms -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/comparing-an-intersec...
