myObjList is an ArrayList<MyObj> containing from 2 to 20,000 objects
state2CodeMap is a HashMap<String, ArrayList<String>> containing an entry for each US state. The associated ArrayList contains a minimum of 1 entry, up to 200 entries.
I need to create a rule that checks all of the MyObj objects in myObjList, gets the appropriate ArrayList from state2CodeMap based on myObj.state and then if myObj.code not memberOf $codeList, run the "then" portion of the rule.
I have created about 60 fairly simple rules, that are working just fine, but this one is a little too complex for me to userstand how to write it in Drools. Looking at this page (http://blog.athico.com/2007/06/chained-from-accumulate-collect.html), I can see that nested "from" seems to be supported, but the page seems to be for Drools 4. Plus, I have had to teach myself Drools in the past week. I could really use some help with this. Any assistance is greatly appreciated!
Squanch that. And squanch this tiny ad:
