>
> Related to CAY-1090 vertical inheritance work, need to make
> EntityInheritanceTree object easier to use. As a part of that will change
> EntityResolver.lookupInheritanceTree() logic that would return NULL if a
> class has no subclasses. Instead this method will return non-null instance
> for any existing entity while a check for subclasses will be performed by
> the callers.
> After doing some local refactoring based on this change, I foudn that it
> actually saved some if/else code, and resulted in a cleaner inheritance
> handling in general. One possible further improvement will be to split
> EntityInheritanceTree functions into "pure metadata" and "behavior" and
> assign the later to the ClassDescriptor (in the same way we split ObjEntity
> and ClassDescriptor responsibilities).
