vtkCellLinks.GetCells (vtkIdType ptId) not accessible from Java wrapper

Support
1

I use vtk 9.5 with java wrapper. vtkCellLinks can be instantiated and built (with BuildLinks()), but GetLink() and GetCells() simply do not appear in the Java wrapper. I can’t figure out how vtkCellLinks can be useful if links cannot be retrieved. Maybe (probably) I miss something.
How can I do to retrieve my links ? Do I have to build in Java a ‘parallel’ structure ?

Any hint will be gratefully appreciated.

You can forget about GetLink(). The return type is not a vtkObject so it won’t be wrapped.

The Java wrapper code does not seem to recognise the return type for GetCells(). I would suggest changing

vtkIdType* GetCells(vtkIdType ptId)

to

long long* GetCells(vtkIdType ptId)

and then rebuild.

Well that doesn’t work, so I tried adding a new method

void GetLink(vtkIdType ptId, vtkIdType& nCells, vtkIdType*& cells) VTK_SIZEHINT(cells, nCells);

void vtkCellLinks::GetLink(vtkIdType ptId, vtkIdType& nCells, vtkIdType*& cells) 
{
  Link& link = this->Array[ptId];
  nCells = link.ncells;
  cells = link.cells;
}

but it doesn’t generate Java wrapper code either. However there are other VTK classes which generate correctly e.g. const vtkIdType* vtkWedge::GetFaceArray()

This is a mystery to me. @dgobbi Do you know where the translation from vtkIdType to long long occurs?
