RE: [rules-users] Intermediate conclusions using strings

I would rather use a class with an Enumeration representing the conclusion. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of David Boaz Sent: 25 August 2008 13:09 To: rules-users(a)lists.jboss.org Subject: [rules-users] Intermediate conclusions using strings Hi all, I have an idea and I want to get the community feedback. Many times there are many ways to reach an intermediate conclusion. This conclusion can be used to derive higher level conclusions or actions. For example, assuming a credit application has several (or) options to conclude whether a parson is classified as gold member. Then, other rules need this information to determine the credit limit for that member. To note, the Person java class doesn't have a specialized attribute for the classification. The classification is only an internal means to simplify the application logic. To solve that problem, I thought to insert a string conclusion to the WM. Something like: rule "gold member if revenue per month > 1000" when ... then insert("gold member") end rule "gold member if total amount > 1000000" when ... then insert("gold member") end ... rule r100 when String(value=="gold member") then... end * Is it an appropriate approach? * I know it ugly to use the same string literal in various rules. Can we avoid that? * Is there a known mechanism to handle these cases?
