How do I inherit from an EDataType [message #423189]

Hello,

if I read the ecore-Metamodel right there is currently no
straightforward way to inherit from a EDataType. What do I do if I want
to have an EClass that inherits from an already existing (non-E) class?

Is there a reason why this is prohibited?

Cheers,
Alexander Dotor

Alexander,

You can use an EClass just like an EDataType in that you can set the
instance class name to some existing Java interface. You can mark the
EClass with isInterface and isAbstract true, so you don't end up with a
generated Impl class that implements that interface. This EClass can
then be used as a super type for your modeled classes.
