推导指引(C++17)

 

定义于头文件 <scoped_allocator>
template< class T > void destroy( T* p );		(since C++11)

使用外部分配器调用 p 指向对象的析构函数，通过调用

std::allocator_traits<OUTERMOST>::destroy(OUTERMOST(*this), p)

其中 OUTERMOST 是通过调用 this->outer_allocator() 返回的类型，然后递归地对该调用的结果调用 outer_allocator() 成员函数，直到达到没有此类成员函数的类型。

参数

p

-

指向即将被销毁的对象的指针

返回值

(无)
