Hello Everyone,
I'm in a need of a way to use a one-time rule to work with a set of
objects. Giving some details, i have a bag of instantiated objects from a
class A. I want to get all those objects and make them atrributes of a
class B with a one-time rule that get all those objects and return a
single B class. I know i can't do it with a declarative rule because when
it matches always return something.
I don't know if i explained it well, but that's it.
Thanks,
Sorry about the bad english (wrote in a hurry),
Leonardo Jr.

I think lazy rules could help you, take look at this section in ATL wiki :
