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

使用外部分配器调用 p 所指向对象的析构函数，通过调用

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

其中 OUTERMOST 类型是通过调用 this - > outer_allocator ( ) ，然后递归调用该调用结果上的 outer_allocator() 成员函数，直到到达没有该成员函数的类型时所返回的类型。

参数

p - 指向即将被销毁对象的指针

返回值

(无)
