[Insight-users] determine class name dynamically

[Ivan Macia]

Hi Bing

You could use the method GetClassName() in itk::Object to obtain the name of
the class as a string and compare it. I ignore if there are any other
methods in ITK for run-time type information.

You can also use the C++ dynamic_cast<>() operator. With this operator you
can make a downcast from a base class to a derived class pointer. If the
conversion is not possible the dynamic_cast operator will return NULL.
Otherwise it will convert the base class pointer to the derived class
pointer. You may check this condition.
