std::bit_not
< cpp | utility | functional
Defined in header <functional>
|
||
template< class T = void > struct bit_not; |
(since C++14) | |
Function object for performing bitwise NOT. Effectively calls operator~ on type T
.
Specializations
The standard library provides a specialization of std::bit_not
when T
is not specified, which leaves the parameter types and return type to be deduced.
function object implementing ~x deducing argument and return types (class template specialization) |
Member types
|
(until C++20) |
Member functions
operator() |
returns the result of bitwise NOT of its argument (public member function) |
std::bit_not::operator()
constexpr T operator()( const T& arg ) const; |
||
Returns the result of bitwise NOT of arg
.
Parameters
arg | - | value to compute bitwise NOT of |
Return value
The result of ~arg.
Exceptions
(none)
Possible implementation
constexpr T operator()(const T& arg) const { return ~arg; } |
