< cpp‎ | memory‎ | unique ptr

Deleter& get_deleter() noexcept; |  | (C++11 起)
const Deleter& get_deleter() const noexcept; |  | (C++11 起)

返回会用于析构被管理对象的删除器对象。

### 参数

（无）

### 返回值

存储的删除器对象。

### 示例

    #include <iostream>
    #include <memory>

    struct Foo
    {
        Foo() { std::cout << "Foo...\n"; }
        ~Foo() { std::cout << "~Foo...\n"; }
    };

    struct D
    {
        void bar() { std::cout << "Call deleter D::bar()...\n"; }
        void operator()(Foo* p) const
        {
            std::cout << "Call delete for Foo object...\n";
            delete p;
        }
    };

    int main()
    {
        std::unique_ptr<Foo, D> up(new Foo(), D());
        D& del = up.get_deleter();
        del.bar();
    }

输出：

    Foo...
    Call deleter D::bar()...
    Call delete for Foo object...
    ~Foo...
