owner_less

  • 아티클

공유된 포인터와 약한 포인트에 대한 소유권 기반의 혼합된 비교를 허용합니다. Returns true if the left parameter is ordered before right parameter by the member function owner_before.

template<class Type>
    struct owner_less; // not defined

template<class Type>
    struct owner_less<shared_ptr<Type> > {
    bool operator()(
        const shared_ptr<Type>& _Left,
        const shared_ptr<Type>& _Right
);
    bool operator()(
        const shared_ptr<Type>& _Left,
        const weak_ptr<Type>& _Right
);
    bool operator()(
        const weak_ptr<Type>& _Left,
        const shared_ptr<Type>& _Right
);
};

template<class Type>
    struct owner_less<weak_ptr<Type> >
    bool operator()(
        const weak_ptr<Type>& _Left,
