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

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

[edit] 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.

function object implementing x & y deducing argument and return types

(since C++14)

[edit] Member types

Type Definition
result_type T
first_argument_type T

[edit] 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

(none)

Possible implementation

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