[henshin-dev] ModelHelper

[Christian Krause <henshin.ck@xxxxxxxxx>]

Hi,

the ModelHelper class in the interpreter plug-in offers very mixed 
functionality. Can we maybe separate the generic EMF-related methods 
from the Henshin-related stuff?

Also the method for registering file extensions is not ideal -- it 
should say in the name that it registers XMI resource handlers. Ideally 
it should also have 2 Boolean parameters for specifying whether the 
resources are packed and whether UUIDs are being used. The latter is 
very important for models that use GMF diagrams, because the UUID 
feature must be turned on for these models! This was also the reason why 
I introduced HenshinResources (see HenshinResource to see how to enable 
the special features).

Gregor, could you maybe have a look at the ModelHelper class?

Cheers,
Christian
