Introduction

It is a stream class to operate on strings of wide characters.

Below is definition of std::wstringstream.

typedef basic_stringstream<wchar_t> wstringstream;

charT − Character type.
traits − Character traits class that defines essential properties of the characters used by stream objects.
int_type − Integer Type.
pos_type − Traints Pos Type.
off_type − Traints Off Type.
allocator_type − Allocator.
