[Insight-users] Inheriting fields from the BSplineDeformableTransform ?

[motes motes]

Ok it seems that BSplineDeformableTransform is not designed to be extended.

1) Not possible to extend InsideValidRegion() since its private.
2) Not possible to access the private fields:

     bool          m_SplineOrderOdd;
     SizeType      m_SupportSize;

no GetMacro.

Currently the best solution as I see it is to extend itkTransform
instead and copy everything from BSplineDeformableTransform to the
subclass. Not a very optimal approach though (a lot of already
existing code is duplicated).

A better alternative would be to change the private visibility of the
fields in the BSplineDeformableTransform to 'protected'. Any comments
on this suggestion?
