Constructs an object of type basic_stringstream.
explicit basic_stringstream( 
   ios_base::openmode _Mode = ios_base::in | ios_base::out 
); 
explicit basic_stringstream( 
   const basic_string<Elem, Tr, Alloc>& _Str, 
   ios_base::openmode _Mode = ios_base::in | ios_base::out 
);
Parameters
_Mode
One of the enumerations in ios_base::openmode._Str
An object of type basic_string.
Remarks
The first constructor initializes the base class by calling basic_iostream(sb), where sb is the stored object of class basic_stringbuf<Elem, Tr, Alloc>. It also initializes sb by calling basic_stringbuf<Elem, Tr, Alloc>(_Mode).
The second constructor initializes the base class by calling basic_iostream(sb). It also initializes sb by calling basic_stringbuf<Elem, Tr, Alloc>(_Str, _Mode).
