Refactoring to Transform Base Class (Extends) to Field + Delegations?

Hi,

Is there a refactoring that will replace a base class with a field of that class's type and possibly introduce delegations to the methods no longer inherited?

If there are third-party (free or open or commercial) that implement such a refactoring, I'd like to know of them, too.

If nothing like this exists, is there a way to partially automate such a transformation?

Thanks.
