Hi Guys, I am new to drools and i have done some PoC of small things. Now i want to implement a business functionality and it seems very complex to me. I didnt get much time to go through docs but i went through it as much as can do. but still no luck My issue is I have list of employee objects it has methods say empId, empPhone and empFName. this employee class has overridden hashcode and equals method. It uses empId and empPhone to check if user is right user. I have hashMap of emp objects this map contains all employees of all depts and locations. I want to check if objects present in list are present in hashmap. if they are present then i want to add them to different list and return corresponding java code is as below List <Emp> empList = new ArrayList<Emp>(); Map<Emp,Emp> map = new HashMap<Emp,Emp>(); for(Emp emp : empList){ if(map.contains(emp)){ // do something } }
I need to convert above code in drools format in drl file. can I iterate list and use contains in when clause ? so that i can put my actions in then. through java i am providing drl with employeelist and hashmap Please help i am in real trouble now I tried doing rule "rule for emp" when //$o : MyClass( id == "1", name == "name" ) empDetails : TempStorage($object : empDetails) empTable: TempStorage($mapObject : empTableData) $mapObject.contains($object) and Emp(empId == $object.empId , empPhone == $object.empPhone) from $object then System.out.println("hiiiii"); end but no luck i get exception as *Unable to resolve ObjectType '$mapObject.contains' : [Rule name='calculation for 10%']* -- View this message in context: http://drools.46999.n3.nabble.com/iterating-through-list-of-object-and-checking-if-object-is-present-in-Hashmap-tp4027505.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
