[Insight-users] itk set\get macro

[Zachary Pincus]

The ITK set/get macros are specifically geared toward subclasses of  
itk::Object (and sub-subclasses, etc. of course), which maintain  
modified-time information (important for pipeline updates, etc.), and  
which have "debug" methods where you can see every change to an object.

Also I think you'll need to use the itkTypeMacro to provide the  
"GetNameOfClass" method that the getters and setters use.

I suggest looking at these macro definitions in itkMacro.h
