std::bit_or<void>: std::bit_or<void>


std::bit_or<void> - std::bit_or<void>


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

std::bit_or<> is a specialization of std::bit_or with parameter and return type deduced.

operator() (public member function)


template< class T, class U>

Returns the result of std::forward<T>(lhs) | std::forward<U>(rhs).

Return value

The result of std::forward<T>(lhs) | std::forward<U>(rhs).


The member type is_transparent indicates to the caller that this function object is a transparent function object: it accepts arguments of arbitrary types and uses perfect forwarding, which avoids unnecessary copying and conversion when the function object is used in heterogeneous context, or with rvalue arguments. In particular, template functions such as std::set::find and std::set::lower_bound make use of this member type on their Compare types.
