STL vector中的reference(2)

原文地址:http://www.cplusplus.com/reference/vector/vector-bool/reference/
public member class
<vector>

std::vector<bool>::reference

class reference;
Reference type

This embedded class is the type returned by members of non-const vector<bool> when directly accessing its elements. It accesses individual bits with an interface that emulates a reference to a bool.

这个内部类是vector<bool>直接访问其元素时返回non-const引用时设计的,它使用模拟成引用的接口访问单个的bits。


Its prototype is:

  • C++98
  • C++11
1 2 3 4 5 6 7 8 9 10 
class vector<bool>::reference { friend class vector; reference() noexcept; // no public constructor public: ~reference(); operator bool () const noexcept; // convert to bool reference& operator= (const bool x) noexcept; // assign from bool reference& operator= (const reference& x) noexcept; // assign from bit void flip(); // flip bit value. };


//翻译的不好的地方请多多指导,可以在下面留言或者点击左上方邮件地址给我发邮件,指出我的错误以及不足,以便我修改,更好的分享给大家,谢谢。
