Hi all,
Where in EMF - if it all - is there code for checking the consistency of
a model against its metamodel? For example, it seems reasonable that
each object (in a model) must be an instance of some non-abstract
meta-class.
I'm trying to compile a complete list of consistency constraints for EMF
models and metamodels.
Many thanks,
Louis.

EMF objects are strongly typed. EObject.eClass() returns an object's
type. It must conform to this type and it's effectively impossible for
it not to. Diagnostician.INSTANCE can be used to validate that all the
other constraints that aren't enforced simply by type safety are respected.

Have a look at EObjectValidator for the basic consistency constraints.

Of course! I hadn't fully understood that consistency is enforced due to
the strong typing of EMF objects.

Perfect, thanks. Just what I was after.
Cheers,
