I was wondering whether or not OCL and Acceleo support working with maps (HashMap,HashSet ...)
I'm trying to wrap a query with a java service and return a hashmap in order to iterate through it in a template. Otherwise I'd have to make two different queries and return two list, one for the keys and another for the values...
Regards

Hi

A Set has been part of OCL (and Acceleo) since forever.

A Map is on the to-do list for OCL 2.5.

Acceleo gives you an ability to invoke Java so you can craft your own.

If you're really enthusiastic you can sort of emulate a Map with a Set
of Tuples.
