std::bit_and

STD：BIT[医]和

Defined in header ​​
template< class T > struct bit_and;​(until C++14)
template< class T = void > struct bit_and;​(since C++14)

函数对象，用于按位执行和。有效呼叫operator&论类型T...

专门性

The standard library provides a specialization of std::bit_and when T is not specified, which leaves the parameter types and return type to be deduced. bit_and function object implementing x & y deducing argument and return types (class template specialization)bit_andfunction object implementing x & y deducing argument and return types (class template specialization)(since C++14)
bit_and<void>function object implementing x & y deducing argument and return types (class template specialization)

成员类型

TypeDefinition
result_type(deprecated in C++17)T
first_argument_type(deprecated in C++17)T
second_argument_type(deprecated in C++17)T

成员函数

operator()returns the result of bitwise AND of two arguments (public member function)

STD：BIT[医]操作员%28%29

T operator()( const T& lhs, const T& rhs ) const;​(until C++14)
constexpr T operator()( const T& lhs, const T& rhs ) const;​(since C++14)

返回按位和lhs和rhs...

参数

lhs, rhs-values to compute bitwise AND of

返回值

结果lhs & rhs...

例外

%280%29

可能的实施

ConstT算子%28%29%28 const T&lhs，const T&rhs%29 const{返回lhs&rhs；}
