Public member functions

enable_shared_from_this::shared_from_this

 

constexpr enable_shared_from_this() noexcept;	(1)
enable_shared_from_this(const enable_shared_from_this<T>&obj) noexcept;	(2)

Constructs new enable_shared_from_this object.

Parameters

obj

-

an enable_shared_from_this to copy

Exceptions

noexcept specification:  

noexcept

  (since C++11)

Example

#include <memory>
 
struct Foo : public std::enable_shared_from_this<Foo> {
    Foo() {}  // implicitly calls enable_shared_from_this constructor
    std::shared_ptr<Foo> getFoo() { return shared_from_this(); }
};
 
int main() {
    std::shared_ptr<Foo> pf1(new Foo);
    auto pf2 = pf1->getFoo();  // shares ownership of object with pf1
}
