std::basic_string_view<CharT,Traits>::swap
|
(since C++17) |
Exchanges the view with that of v.
Parameters
| v | - | view to swap with |
Return value
(none)
Complexity
Constant.
Example
#include <iostream>
#include <string_view>
int main()
{
std::string_view a = "AAA";
std::string_view b = "BBBB";
std::cout << "Before swap:\n"
"a = " << a << "\n"
"b = " << b << "\n\n";
a.swap(b);
std::cout << "After swap:\n"
"a = " << a << "\n"
"b = " << b << '\n';
}Output:
Before swap:
a = AAA
b = BBBB
After swap:
a = BBBB
b = AAASee also
