eopposite on a map [message #422873] Wed, 17 September 2008 19:26 Go to next message

Hi,

I have a map from String to Objects in my model, and this map is a
feature of class A. Is it possible to directly access class A from any
of my objects in the map (e.g. via eContainer() or something similar)?

Thanks a lot
Luzi

Luzi,

The map entries themselves can use eContainer() to access the A instance.

Ed,

thanks for the quick reply!
Do the objects themselves have no possibility to access the class A
(without modelling it with an extra reference)?

Luciano,

Which objects? The map entry will always have a pointer. The objects
would need a bidirectional reference back to the map entry, or if it's a
containment reference, call eContainer().eContainer()...
