explicit basic_stringstream(ios_base::openmode which);

1

#

Effects: Initializes the base class withbasic_iostream<charT, traits>(addressof(sb)) ([iostream.cons]) andsb withbasic_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 withbasic_iostream<charT, traits>(addressof(sb)) ([iostream.cons]) andsb withbasic_stringbuf<charT, traits, Allocator>(s, which).

🔗

basic_stringstream(ios_base::openmode which, const Allocator& a);

3

#

Effects: Initializes the base class withbasic_iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb withbasic_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 withbasic_iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb withbasic_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 withbasic_iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb withbasic_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 withbasic_iostream<charT, traits>(addressof(sb)) ([iostream.cons]) and sb withbasic_stringbuf<charT, traits, Allocator>(s, which) ([stringbuf.cons]).

🔗

template<class T> explicit basic_stringstream(const T& t, ios_base::openmode which = ios_base::out | ios_base::in); template<class T> basic_stringstream(const T& t, const Allocator& a); template<class T> basic_stringstream(const T& t, ios_base::openmode which, const Allocator& a);

8

#

Let which be ios_base​::​out | ios_base​::​in for the overload with no parameter which, anda be Allocator() for the overload with no parameter a.

9

#

Constraints: is_convertible_v<const T&, basic_string_view<charT, traits>> is true.

10

#

Effects: Initializes the base class with addressof(sb), and direct-non-list-initializes sb with t, which, a.

🔗

basic_stringstream(basic_stringstream&& rhs);

11

#

Effects: Move constructs from the rvalue rhs.

This is accomplished by move constructing the base class, and the containedbasic_stringbuf.

Then calls basic_istream<charT, traits>​::​set_rdbuf(addressof(sb)) to install the contained basic_stringbuf.
