[rules-users] foreach in drl file

[Joe White]

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

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
