std::bitset::reference
class reference; | | |
|---|
大std::bitset类包括std::bitset::reference作为一个可公开访问的嵌套类。此类用作代理对象，允许用户与位集的单个位进行交互，因为标准C++类型%28类引用和指针%29的构建不够精确，无法指定单个位。
主要用途std::bitset::reference提供一个可以从operator[]...
通过std::bitset::reference可能会读取或写入整个基础位集。
成员函数
(constructor) | constructs the reference. Accessible only to std::bitset itself (private member function) |
|---|---|
(destructor) | ~reference (public member function) |
operator= | assigns a bool to the referenced bit (public member function) |
operator bool | returns the referenced bit (public member function) |
operator ~ | returns inverted referenced bit (public member function) |
flip | flips the referenced bit (public member function) |
