Re: [rules-users] iterating over objects in a StatelessKnowledgeSession

Hi Mark, I want this for a unit test. It will verify that the stateless session contains only expected objects after execution. I don't want to write a new query that will be used only in the unit test. Currently it is possible to iterate over all objects in a StatefulKnowledgeSession through its getObjects method. However it is not supported by default on the StatelessKnowledgeSession. I've created a custom command for getting the objects. Its execute method looks like this: public Iterator< ? > execute(ReteooWorkingMemory session) { Iterator<?> objects = session.iterateObjects( filter ); session.getBatchExecutionResult().getResults().put(identifier, objects); return objects; } Another thing to note is that StatelessKnowledgeSession.execute(Command command) method first executes all given commands and then calls session.fireAllRules. So if you want to insert some objects and run a query you'll pass some insert commands and a query command. However the query will be executed before the fireAllRules call and so it won't return anything.Alternatively you could pass in a fireAllRules command as well, which will work fine. The fireAllRules will be executed twice but that is not a big deal. Another issue is that the query command makes it difficult to pass in query arguments that are known only after the rules execution. Because you have to specify the query before the fireAllRules execution. I guess you could create your own command and do all logic there but this is not very nice. Just my 2c.
