enable_shared_from_this Class
Helps generate a shared_ptr.
template<class Ty>
class enable_shared_from_this {
public:
shared_ptr<Ty> shared_from_this();
shared_ptr<const Ty> shared_from_this() const;
protected:
enable_shared_from_this();
enable_shared_from_this(const enable_shared_from_this&);
enable_shared_from_this& operator=(const enable_shared_from_this&);
~enable_shared_from_this();
};
Parameters
- Ty
The type controlled by the shared pointer.
Remarks
The template class can be used as a public base class to simplify creating shared_ptr Class objects that own objects of the derived type:
class derived
: public enable_shared_from_this<derived>
{
};
shared_ptr<derived> sp0(new derived);
shared_ptr<derived> sp1 = sp0->shared_from_this();
The constructors, destructor, and assignment operator are protected to help prevent accidental misuse. The template argument type Ty must be the type of the derived class.
