[rules-users] foreach in drl file

[Ingomar Otter]

How about

when
	Time(value==10)   //it's 10 o'clock
         $aFriend: Friend() //any friend in the working memory
then
	//RHS will be fired for each friend if it's 10 o'clock
end

or:

when
	Time(value==10) //is it 10?
	$self:Self()  //get a handle to yourself
	$friend: Friend( name in "Mike", "Tom", "Anna" ) from  
$self.friends  //match your friends named Mike, Tom or Anna.
then
..  //will be fired for each of your friends that are called either  
Mike, Tom or Anna
end

Depending on the actual problem there are a lot of ways of doing this.  
If you provide a 'less artificial' example we may be able to help ;-)

Please study Drools Manual (4.07) chapter 6.5.2, it has nice tiny  
examples.



Cheers,
