推导指南(C++17)

 

定义在头文件 <scoped_allocator> 中
template< class T > void destroy( T* p );		(自 C++11 起)

使用外部分配器调用 p 指向的对象的析构函数，方法是调用

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

其中 OUTERMOST 是通过调用 this->outer_allocator()，然后对该调用结果的 outer_allocator() 成员函数进行递归调用（直到到达没有此成员函数的类型）而返回的类型。

参数

p

-

指向将要销毁的对象的指针

返回值

(无)
