std::bit_or: std::bit_or

NAME

std::bit_or - std::bit_or

Synopsis


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


Function object for performing bitwise OR. Effectively calls operator| on type T.

Specializations


The standard library provides a specialization of std::bit_or 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)
bit_or<void> (class template specialization)

Member types


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

Member functions


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


 std::bit_or::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 OR of lhs and rhs.

Parameters


lhs, rhs - values to compute bitwise OR 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;
  }
