🔗
explicit basic_stringstream(ios_base::openmode which);
1
#
Effects: Initializes the base class with basic_­iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb with basic_­stringbuf<charT, traits, Allocator>(which).
🔗
explicit basic_stringstream( const basic_string<charT, traits, Allocator>& s, ios_base::openmode which = ios_base::out | ios_base::in);
2
#
Effects: Initializes the base class with basic_­iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb with basic_­stringbuf<charT, traits, Allocator>(s, which).
🔗
basic_stringstream(ios_base::openmode which, const Allocator& a);
3
#
Effects: Initializes the base class with basic_­iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb with basic_­stringbuf<charT, traits, Allocator>(which, a) ([stringbuf.cons]).
🔗
explicit basic_stringstream( basic_string<charT, traits, Allocator>&& s, ios_base::openmode which = ios_base::out | ios_base::in);
4
#
Effects: Initializes the base class with basic_­iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb with basic_­stringbuf<charT, traits, Allocator>(std​::​move(s), which) ([stringbuf.cons]).
🔗
template<class SAlloc> basic_stringstream( const basic_string<charT, traits, SAlloc>& s, ios_base::openmode which, const Allocator& a);
5
#
Effects: Initializes the base class with basic_­iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb with basic_­stringbuf<charT, traits, Allocator>(s, which, a) ([stringbuf.cons]).
🔗
template<class SAlloc> explicit basic_stringstream( const basic_string<charT, traits, SAlloc>& s, ios_base::openmode which = ios_base::out | ios_base::in);
6
#
Constraints: is_­same_­v<SAlloc,Allocator> is false.
7
#
Effects: Initializes the base class with basic_­iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb with basic_­stringbuf<charT, traits, Allocator>(s, which) ([stringbuf.cons]).
🔗
basic_stringstream(basic_stringstream&& rhs);
8
#
Effects: Move constructs from the rvalue rhs.
This is accomplished by move constructing the base class, and the contained basic_­stringbuf.
Then calls basic_­istream<charT, traits>​::​set_­rdbuf(addressof(sb)) to install the contained basic_­stringbuf.
