[rules-users] java void in LHS

[Anstis, Michael (M.)]

I'd assume you need two rules:-

rule test123a
    when
	$c : Cheese()
	$ct : CheeseType(cheese = $c)
    then
	$ct.setPrice("cheap");
	update($ct);
end

rule test123b
    when
	$c : Cheese( type = "myType" )
	CheeseType(cheese = $c, price = "cheap" )
    then
	...
end
 
Java dialect doesn't support object graphs - I think MVEL does but I'm
unfamilair with the syntax.

You could also replace the two patterns (one for Cheese and the other
CheeseType) with an eval but you'll loose performance.

Forgive me if I'm wrong and this is 3.0.x and not 4.0.x.

With kind regards,

Mike

Subject: [rules-users] java void in LHS

Hi all,

I would like to insert a java void to my condition(LHS). Is there anyway
to
do that? Like an example below, how can I set something to my object
before
evaluate it.


rule test123
    when
         cheese: Chesse()

--->>> chess.getType().setPrice("cheap");

         eval (chesse.getType () == "myType")


    then
           .....
    end



Thanks,

Tim
