RE: [rules-users] foreach in drl file

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!
