Re: [rules-users] Smart Templates

Ok, thanks, but how do I do that in a template? ________________________________ From: Wolfgang Laun-2 [via Drools] [mailto:ml-node+3011098-67106608-404175@n3.nabble.com] Sent: 01 June 2011 15:46 To: Mullard, Christopher Subject: Re: [rules-users] Smart Templates In the Drools Expert manual, search for "And, finally, here is an example of Import, Variables and Functions."

Call JAva code if you don't want to put it all into DRL function, or import from Java in the first place. Both "import" and "function" can be used in spreadsheets. -W 2011/6/1 ChrisMu <[hidden email] <http://user/SendEmail.jtp?type=node&node=3010989&i=0> > Agreed, but this was just an example - if the function required something more complicated - say a DB lookup, could it be done? ________________________________ From: Wolfgang Laun-2 [via Drools] [mailto:[hidden email] <http://user/SendEmail.jtp?type=node&node=3010490&i=0> ] Sent: 01 June 2011 12:40 To: Mullard, Christopher Subject: Re: [rules-users] Smart Templates If there are just 2 types (IRDELTA, COMLEASEDELTA) you can add a function that computes this from the 3-letter name. -W 2011/6/1 ChrisMu <[hidden email] <http://user/SendEmail.jtp?type=node&node=3010275&i=0> > Possibly. Let me try again with what I'm trying to achieve. Given this excerpt from a decision table: Basically I want to be able to specify a template that says 'If Arg0 is a currency, output RiskType IRDELTA (and currency), if Arg0 is a commodity (begins with 'X') then output RiskType COMLEASEDELTA (and commodity). When fed with data, this would generate the rules: when Arg0 = USD, output RiskType IRDELTA, USD when Arg0 = GBP, output RiskType IRDELTA, GBP etc when Arg0 = XAU, output RiskType COMLEASEDELTA, XAU etc In this way theRiskType name is inferred from the data when the rules are generated. It can be done by explicitly stating all possible combinations as in the decision table above but that gets tedious quickly. I wanted to have a more general template that could generate all the specific rules instances. Does that make more sense? Thanks Chris ________________________________ From: Wolfgang Laun-2 [via Drools] [mailto:[hidden email] <http://user/SendEmail.jtp?type=node&node=3010119&i=0> ] Sent: 01 June 2011 11:21 To: Mullard, Christopher Subject: Re: [rules-users] Smart Templates I don't want to confuse you, but have you considered not using templates at all? If you can generate N rules from N objects containing different literals for matching a fact or for updating a fact field, then you can achieve the same thing with a single rule and additional facts containing those literal values. rule "one 4 all" when   Service( $name: name, $value: value )   $sb: ServiceBean( name == $name, value == $value ) then   # RiskType ... is what?   ...$value..., ...$sb.getType()... end -W _______________________________________________ rules-users mailing list [hidden email] <http://user/SendEmail.jtp?type=node&node=3010097&i=0> https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010097.html To unsubscribe from Smart Templates, click here. ============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ============================================================================== ________________________________ View this message in context: RE: [rules-users] Smart Templates <http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010119.html> Sent from the Drools: User forum mailing list archive <http://drools.46999.n3.nabble.com/Drools-User-forum-f47000.html> at Nabble.com. _______________________________________________ rules-users mailing list [hidden email] <http://user/SendEmail.jtp?type=node&node=3010275&i=1> https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list [hidden email] <http://user/SendEmail.jtp?type=node&node=3010275&i=2> https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010275.html To unsubscribe from Smart Templates, click here. ============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ============================================================================== ________________________________ View this message in context: RE: [rules-users] Smart Templates <http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010490.html> Sent from the Drools: User forum mailing list archive <http://drools.46999.n3.nabble.com/Drools-User-forum-f47000.html> at Nabble.com. _______________________________________________ rules-users mailing list [hidden email] <http://user/SendEmail.jtp?type=node&node=3010989&i=1> https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list [hidden email] <http://user/SendEmail.jtp?type=node&node=3010989&i=2> https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010989.html To unsubscribe from Smart Templates, click here. ============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ============================================================================== ________________________________ View this message in context: RE: [rules-users] Smart Templates <http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3011008.html> Sent from the Drools: User forum mailing list archive <http://drools.46999.n3.nabble.com/Drools-User-forum-f47000.html> at Nabble.com. _______________________________________________ rules-users mailing list [hidden email] https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list [hidden email] https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3011098.html To unsubscribe from Smart Templates, click here <http://drools.46999.n3.nabble.com/template/NamlServlet.jtp?macro=unsubscr... . =============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html =============================================================================== -- View this message in context: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3011115.html Sent from the Drools: User forum mailing list archive at Nabble.com.
