Additional InformationBelow is a grep on the Functor and Function namespace. Ideally, all concerned functors should be there.

 A patch was committed on Feb 24, 2009 for the functors in the Review directory.

 Tom, maybe we should bring up moving these out of review on the developer list?

 itkChangeLabelImageFilter -- the ChangeLabel functor refuses to allow operator() to be const. Will look at fixing after other cases.

 Patched ChangeLabelImageFilter to make operator() const:
http://www.itk.org/cgi-bin/viewcvs.cgi/Code/BasicFilters/itkChangeLabelImageFilter.h?root=Insight&r1=1.6&r2=1.7&sortby=date [^]

It needed a little work because according to http://www.sgi.com/tech/stl/Map.html: [^]
"Since operator[] might insert a new element into the map, it can't possibly be a const member function. Note that the definition of operator[] is extremely simple: m[k] is equivalent to (*((m.insert(value_type(k, data_type()))).first)).second. Strictly speaking, this member function is unnecessary: it exists only for convenience."

 I checked in fixes for all such classes.
