Re: [rules-users] Evaluate rules for multiple facts of the same type within a StateuflSession

There's an interesting note to be made in addition to the Section "Fact Classification" in the whitepaper. class Param { boolean creditcard; Product product; int discount, } is easy enough to handle (with product == null to indicate no product test). But what if you'd like to test for more than one product? class Param { boolean creditcard; Set<Product> products; int discount, } The test for one set being a subset of another isn't the problem, but now you can create Param instances that don't define mutually exclusive cart values, e.g.: Cart: true, {A, B, C}. Param: true, {A}, 10 Param: true, {A, B}, 12 In this case you might, in the rule pairing off a Cart and a Param, a) ensure that there is no other matching Param with a higher discount b) use a salience expression based on discount -W On 13/02/2013, pdario <dario.piantanida(a)gmail.com&gt; wrote:
