void swap(basic_istringstream& rhs);
Effects: Equivalent to: basic_istream<charT, traits>::swap(rhs); sb.swap(rhs.sb);
template<class charT, class traits, class Allocator> void swap(basic_istringstream<charT, traits, Allocator>& x, basic_istringstream<charT, traits, Allocator>& y);
Effects: Equivalent to: x.swap(y).
