C++: type_info to distinguish types

Question

I know that compilers have much freedom in implementing std::type_info functions\' behavior.

I\'m thinking about using it to compare object types, so I\'d l

Answer 1

You can store it like this.

class my_type_info
{
public:
     my_type_info(const std::type_info& info) : info_(&info){}
     std::type_info get() const { return *info_;}
private:
     const std::type_info* info_;
};

EDIT:

C++ standard 5.2.8.

The result of a typeid expression is an lvalue of static type const std::type_info...

Which means you can use it like this.

my_type_info(typeid(my_type));

The typeid function returns an lvalue (it is not temporary) and therefore the address of the returned type_info is always valid.
