[Insight-users] itk typemaps again !

[Gaetan Lehmann]

Hi Brad,

I'm again with typemaps in ITK (with a little more experience than last  
time).
I have wrapped ImageToVTKImageFilter and VTKImageToImageFilter and have  
sucessfully define typemaps for vtkImageExport and vtkImageData  
(http://voxel.jouy.inra.fr/darcs/itkvtk/).

Now I try to do a little more: I want to add typemaps for  
std::vector<...>. It's very simple with swig and works well  
(http://www.swig.org/Doc1.3/Library.html):

   %include "std_vector.i"
   %template(DoubleVector) std::vector<double>;

is enough to wrap vector<double>. But I can't make it work with ITK.
The class DoubleVector is defined, so I can say the %template directive  
does something. However, the type of object returned by an itk method is  
different of type of  DoubleVector.

DoubleVector ->  _p_std__vectorTdouble_t
itk method   ->  _p_std__vectorTdouble_std__allocatorTdouble_t_t

In a pure SWIG program, this is not the case. All are of type  
_p_std__vectorTdouble_std__allocatorTdouble_t_t.

Do you know if that difference of type can explain why typemap don't work ?
And do you know why we have this difference of type with cableswig and not  
with swig alone ?

Regards,

Gaetan
