Limited collection attributes
Issue #125
new
It would be useful if one could limit a collection attribute so that it excludes contributions from specific subtrees.
Say for example that we have the collection attribute wornHats
that collects hats worn by different agents in a world:
coll Collection<Hat> World.wornHats()
[new LinkedList<Hat>()]
with add
root World;
Agent contributes myHat()
when hasHat()
to World.hats()
for world();
We have two agents: Cat
and Person
, as well as three entities: Car
, Train
and Boat
. People and cats can wear hats in cars and trains, but not boats. Due to the wind on a boat the hat can not be worn, only carried. So it would be useful if we can somehow exclude all boats from the collection traversal:
World.wornHats() excludes Boat;
This has the additional advantage of possibly lower collection time since fewer nodes will be searched.

Fix: entities->agents

Use case? JModelica?
Workaround: implement an empty traversal method
