[henshin-dev] MappingList

[Christian Krause <henshin.ck@xxxxxxxxx>]

Hi,

I have the following suggestion to get rid of the nasty 
HenshinMappingUtil class:

We define an interface MappingList in the model package which extends 
EList<Mapping> (we can also name it MappingEList if you prefer). In this 
interface, we define all the functions from the utility class that we 
need. Then we override every method in the model interfaces that return 
an EList<Mapping> such that they return a MappingList. Of course we also 
need a MappingListImpl.

I would not touch the Ecore model because I think it is important for 
the edit and editor plug-ins that it returns a list of Mappings, and not 
a MappingList.

Do you think this is ok? Can anybody do it? The HenshinMappingUtil class 
should be marked as deprecated then. We can then update step-wise all of 
our code (HenshinMappingItil will still work).

Cheers,
Christian
