[Insight-users] itkGetMacro vs. itkGetConstMacro

[HIRAKI Hideaki]

Hello,

In many classes, itkGetMacro is used to provide access to their data 
members and prohibits 'Get' a data member of a 'const' object. I could 
workaround the problem by const_cast (and there are some classes that 
use itkGetConstMacro to allow this kind of operation). But it seems to 
be easier and safe to change the definition of itkGetMacro as 
itkGetConstMacro. Why the two macro need to be differentiated? Is 
there a case itkGetMacro returns a lawbreaker such as a pointer?

Thanks,
