NAME

std::bit_and - std::bit_and

Synopsis

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

Function object for performing bitwise AND. Effectively calls operator& on type T.

Specializations

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.
(since C++14)
bit_and<void> function object implementing x & y deducing argument and
(C++14) return types
(class template specialization)

Member types

Type Definition
result_type (deprecated in C++17)(removed in C++20) T
first_argument_type (deprecated in C++17)(removed in C++20) T
second_argument_type (deprecated in C++17)(removed in C++20) T

These member types are obtained via publicly inheriting (until C++11)
std::binary_function<T, T, T>.

Member functions

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

std::bit_and::operator()

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)

Returns the result of bitwise AND of lhs and rhs.

Parameters

lhs, rhs - values to compute bitwise AND of

Return value

The result of lhs & rhs.

Exceptions

May throw implementation-defined exceptions.

Possible implementation

constexpr T operator()(const T &lhs, const T &rhs) const
{
return lhs & rhs;
}
