Re: [rules-users] New to Drools. Is it possible to test inverse conditions?

Dear Mauricio: Thank you very much for your quick response. If I understood Drools rules documentation, not(Person(age > 30)) means "There is no Person fact in working memory with age > 30". Isn't it? I would like to write in DRL "Retrieve Person facts in working memory with age not greater than 30", not as Person (age <= 30), but using "age > 30" as this is the string that the user will provide. I think it should be some way to do this in DRL. If not, I will have to implement some kind of "inverse condition translator", which converts restrictions to their opposites, something like invertContition("age > 30") returns "age <= 30". I would like not to write this kind of translator. Thank you again for your time.
