[Insight-developers] SmartPointer null check

[Miklos Espak]

Hi,

would it be possible to make a NULL check in itk::SmartPointer::operator->
and operator* ?

I thought an std::runtime_error (or derivant) could be thrown if m_Pointer
is 0. In this way the application would not crash on null pointer
dereference but it could be caught from a GUI eventually. That could spare a
lot of null checks in the code.

Sorry, if this is a recurring topic of discussion or it is already
implemented in ITK 4.0. I use 3.20.0 as part of MITK.

Best regards,
Miklos Espak
