Phil, maybe you can tell us what you are trying to do? Are you talking about the RHS? --Ingomar Am 16.02.2009 um 23:15 schrieb can_man(a)gmx.de:

Phl, I am still not quite there. class, e.g. "Golfer", and addes the conditions in the collection to my rule with "ANDs" So the condition is where? What I would be looking for is a plain text description of the rule, ie. "find all serial numbers of all Golfer objects that have ..." Or something like that. Prose is usually a fairly good starting point for transcribing into rules/drl. Afaik "foreach" loop / iterations is not supported in the LHS per se. They are also not needed as the pattern matcher will just do the right thing. The same result can be achieved in a 'proper' declarative way, (whatever that means ;-) ). Therefore the question about the "what". --I Am 16.02.2009 um 23:58 schrieb can_man(a)gmx.de:

In the case below you don't need to iterate manually. You can use the "contains" LHS element. Take a look at the manual and you will see it. Or you can insert your List directly and use the "from" LHS element Using from it might look like: rule "test" when String(this=="10") //<--The time friends : List() //<--Your friends collection String(this=="myFriend") from friends then System.out.println("HIT"); end -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of can_man(a)gmx.de Sent: Monday, February 16, 2009 4:40 PM To: Rules Users List Subject: Re: [rules-users] foreach in drl file Thanks for the reply Ingomar. I will try, hopefully it is a bit clearer this time. friends = ['Mike', 'Tom', 'Anna'] // this is the collection I want to itterate over time = 10 When my 'friend' is one of 'friends' and time is 10 o'clock then ring my alarm. Hope this shows where I would like the collection to get into play. Thank you, Phil -- Jetzt 1 Monat kostenlos!

Phil, Take a look at the manual and look for the "forall" LHS conditional element if you can pass all of your objects individually. Or if you must pass your items into WM as a List then take a look at the "collect" LHS element examples. In your example if you wanted to say "All Golfers have red pants" it would look something like import com.sample.Golfer; import java.util.List; import java.util.ArrayList; rule "test" when $list : List() //<--The list you use insert into working memory ArrayList( size == $list.size) from collect (Golfer(pantsColor=="red") from $list) then System.out.println("HIT"); End I didn't run it but you get the idea.

I would like to use a template drl file together with a java class. Both the LHS and RHS should contain variables, where the LHS should itterate over a collection in the "when" part. So for example, in the golf example, I would like a foreach which itterates through a list in my java class, e.g. "Golfer", and addes the conditions in the collection to my rule with "ANDs". rule "find solution" when // cut Golfer( @foreach{item : products} - @{item.serialNumber} @end{} ) then // do something end My problem is that I don't really know how to write the foreach syntax. Hope this is clear. Thank you. Phil -- Jetzt 1 Monat kostenlos!
