[ITK] [ITK-dev] itk::DynamicCast<>() and itk::ConstCast<>() working with itk::SmartPointer<>

[Bradley Lowekamp]

Hello Stephane,

Thank you for considering contributing this upstream.

So your suggestions to change:

dynamic_cast<SomeOtherType*>(smartPointer.GetPointer())

to

itk::DynamicCast<SomeOtherType>(smartPointer)


While this may save a few characters on a line I am not sure it is worth the trouble. 



Also the declaration of ConstCast could use some additional consideration. You may only want one template parameter, there T1 and T2 are always the same. The const_cast operator does not do any other type conversion other than changing the const qualifier or volatile, so this template parameter change would help to enforce that.
 

Brad
