[Insight-users] how to use itk::RegularExpressionSeriesFileNames

[Luis Ibanez]

Hi Darren,

Thanks for posting the method for printing filenames.
It looks reasonable to add it to the class.


1)  Note that it may be more general if it takes as second
     argument a std::ostream, just as the PrintSelf() method
     does.

     In that way, it could be used for sending the list of
     filenames to a file, as well as to the standard output.


2)   The .c_str() doesn't seem to be necessary here.
      It should be fine to call (*nameIdx) as you suggest.


   Regards,


        Luis
