[Insight-developers] Const Image Iterators

[Luis Ibanez]

Hi,

We don't have yet  Const iterators for going
through images declared as ConstPointers.

At first view the solution seems to duplicate the
base ImageIteratorWithIndex class to create a
ConstImageIteratorWithIndex.   This second
will have a constructor with a ConstPointer to an
image and will lack the Set() method. It will allow
to perform only Get()'s.

Then... should we duplicate the other iterators deriving
from ImageIterartorWithIndex ?

This is how it is done in STL, it seems to be the
only way to get a consistent set of iterators


Any ideas ?


Thanks

Luis
