Hi,

How to get the root class of the Model package instance ? Is there any API for that ?

Best Regards,

What do you mean by "root" class. A class at the root of an inheritance
tree (i.e. the super-most class) or a containment tree (i.e. a class not
contained in anything but itself)? In any case, I think you'll have to
do a topological sort yourself.

Hello Vaibhav,

Assuming that you are looking to get the Root container of the EPackage doing a

EcoreUtil.getRootContainer(eClass)

and getting the first child should work (again assuming that you have a single root). If you already have a handle to the EPackage then only the second part is enough.
