推导指引(C++17)

 

定义于头文件 <scoped_allocator>
inner_allocator_type& inner_allocator() noexcept;	(1)	(C++11 起)
const inner_allocator_type& inner_allocator() const noexcept;	(2)	(C++11 起)

获得到用于声明此 scoped_allocator_adaptor 的内层分配器的引用。

若 sizeof...(InnerAllocs) == 0 ，即未声明内层分配器，则返回 *this 。否则返回到 std::scoped_allocator_adaptor<InnerAllocs...> 的一个引用，即由 *this 的所有内层分配器组成的有作用域分配器，其首个内层分配器变为外层分配器。

参数

（无）

返回值

到内层分配器的引用，它自身是 std::scoped_allocator_adaptor 。
