[Insight-users] Polymorphism while using Registration Framework

[Stefan König]

Additional, why this won't work?

	typedef itk::Transform< double, Dimension > TransformType;
	TransformType::Pointer foo = createANonAbstractObject();
	m_pRegistrator->SetTransform(foo);

I know, TransformType is abstract, but creating a pointer and using it
with polymorphism should be possible?
