std::bitset::reference

STD：：位集：：参考

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 boolreturns the referenced bit (public member function)
operator ~returns inverted referenced bit (public member function)
flipflips the referenced bit (public member function)

STD：：位集<N>*参考：：~参考

~reference()​​

摧毁了引用。

STD：：位集<N>*参考：：操作员=

reference& operator=( bool x reference& operator=( const reference& x ​​

为引用的位分配一个值。

参数

x-value to assign

返回值

*this...

例外

(none)(until C++11)
noexcept specification: noexcept(since C++11)

STD：：位集<N>*参考资料：：操作人员bool

operator bool() const;​​

返回引用位的值。

参数

%280%29

返回值

参考位。

例外

(none)(until C++11)
noexcept specification: noexcept(since C++11)

<N>*参考资料：：操作员~

bool operator~() const;​​

返回引用位的逆位。

参数

%280%29

返回值

被引用位的逆位。

例外

(none)(until C++11)
noexcept specification: noexcept(since C++11)

STD：：位集<N>*参考资料：：翻转

reference& flip(​​

反转所引用的位。

参数

%280%29

返回值

*this...

例外

(none)(until C++11)
noexcept specification: noexcept(since C++11)

另见

operator[]accesses specific bit (public member function)
