std::swap(std::basic_string): std::swap(std::basic_string)

NAME

std::swap(std::basic_string) - std::swap(std::basic_string)

Synopsis

template< class CharT, class Traits, class Alloc >
void swap( std::basic_string<CharT, Traits, Alloc> &lhs, (until C++17)
std::basic_string<CharT, Traits, Alloc> &rhs );
template< class CharT, class Traits, class Alloc >
void swap( std::basic_string<CharT, Traits, Alloc> &lhs, (since C++17)
std::basic_string<CharT, Traits, Alloc> &rhs ) noexcept(/* see below */);

Specializes the std::swap algorithm for std::basic_string. Swaps the contents of lhs and rhs. Equivalent to lhs.swap(rhs).

Parameters

lhs, rhs - strings whose contents to swap

Return value

(none)

Complexity

Constant.

Exceptions

                                  (since C++17)
