推导指引(C++17)

 

在标头 <scoped_allocator> 定义
outer_allocator_type& outer_allocator() noexcept;	(1)	(C++11 起)
const outer_allocator_type& outer_allocator() const noexcept;	(2)	(C++11 起)

获得到用于声明此类的外层分配器的引用。

1) 返回 static_cast<OuterAlloc&>(*this)。

2) 返回 static_cast<const OuterAlloc&>(*this)。

参数

（无）

返回值

到 OuterAlloc 的引用。
