[Insight-developers] SmartPointer and Get/Set Input/Output

[Bill Hoffman]

One more note on the SmartPointer type conversion.
During construction, the = operator will not cast smart pointers to
parent classes, so you have to use the constructor calling conversion
when initializing smart pointers.

For example (given class A and B where B inherits from A) :

// Create a B smartpointer
B::Pointer bptr(B::New());

// This will NOT compile
A::Pointer p = bptr;

// This will compile
A::Pointer p(bptr);
