How to perform a dynamic_cast with a unique_ptr?

Question

I have a class hierarchy as follows:

class BaseSession : public boost::enable_shared_from_this
class DerivedSessionA : public BaseSession
         


        

Answer 1

Simply get the stored pointer using the std::unique_ptr<>::get() method:

Func(dynamic_cast(shared_from_this().get()))

that if shared_from_this() has that prototype:

std::unique_ptr& shared_from_this();
