Getting rid of fully qualified type names in ocl expressions [message #1006546]

Hi,

In the OCL Example console (mature console) I need to use fully qualified type identifiers. Does OCL have some built-in mechanism to let me use unqualified type identifiers, e.g. Library instead of library::Library instead?

If there's no builtin mechanis, is it possible to hack the (again, mature) interpreter to find types magically, e.g. by inspecting registered EPackages?

Cheers,
Felix

Hi

The basic construction of an EcoreEnvironment takes a package registry.
You could poke as many packages as you like in to the registry.

Hi Ed,

qualified classifier names are not the problem. I want to dynamically resolve _unqualified_ classifier names against registered package. I could then just write "Author.allInstances()" instead of "library::Author.allInstances()". I think I could try to customize EcoreEnvironment.lookupClassifier() to implement such a dynamic cross-package lookup.

Hi

I think you may find lookupPackage easier. There is already a lookup for
no explicit package so you just need to broaden it.
