Sorry, where should we look in the manual for this? _____ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Edson Tirelli Sent: Tuesday, May 27, 2008 11:14 AM To: Rules Users List Subject: Re: [rules-users] DSL/DRL Problem Do you mean like: There is a client - which is adult - whose wife is adult Mapped to: Client( age > 17, spouse.age > 17 ) Take a look at the manual and check for the "-" special character. []s Edson 2008/5/27 <ringsah(a)comcast.net <mailto:ringsah@comcast.net> >: Hi All, I am new to Drools - my company is evaluating it for use in a project. We are doing a proof of concept, and we are developing a DSL. One of our DSL expressions is "client is an adult" which is defined as Client(age > 17) The problem we have is that there are many different types of people in our system that we would like to test for adulthood. For example, we have the client's spouse (Client.spouse), and the clients children (Client.children), who we also want to test for adulthood. Do we need to make a different DSL expression for each case, or is there a way to "genericize" the DSL expression so it could be used for any person?
