27.8 String-based streams [string.streams]

27.8.3 Class template basic_istringstream [istringstream]

27.8.3.1 basic_istringstream constructors [istringstream.cons]

explicit basic_istringstream(ios_base::openmode which = ios_base::in);

1

Effects: Constructs an object of class basic_istringstream<charT, traits>, initializing the base class with basic_istream(&sb) and initializing sb with basic_stringbuf<charT, traits, Allocator>(which | ios_base::in)) ([stringbuf.cons]).

explicit basic_istringstream( const basic_string<charT, traits, Allocator>& str, ios_base::openmode which = ios_base::in);

2

Effects: Constructs an object of class basic_istringstream<charT, traits>, initializing the base class with basic_istream(&sb) and initializing sb with basic_stringbuf<charT, traits, Allocator>(str, which | ios_base::in)) ([stringbuf.cons]).

basic_istringstream(basic_istringstream&& rhs);

3

Effects: Move constructs from the rvalue rhs. This is accomplished by move constructing the base class, and the contained basic_stringbuf. Next basic_istream<charT, traits>::set_rdbuf(&sb) is called to install the contained basic_stringbuf.
