Unable to instantiate istring_iterator using wistringstream interface

Question

I am trying to break a string using the method found in this thread , but I am trying to adapt it to wstring. However, I came across a strange mistake. Check the code:

#include <iostream>
#include <sstream>
#include <string>
#include <vector>
#include <algorithm>
#include <iterator>

using namespace std;

int main(void)
{
    wstring str(L"Börk börk");
    wistringstream iss(str);
    vector<wstring> tokens;
    copy(istream_iterator<wstring>(iss), // I GET THE ERROR HERE
         istream_iterator<wstring>(),
         back_inserter< vector<wstring> >(tokens));

    return 0;
}

The exact error message is:

error: no matching function for call to 'std::istream_iterator<std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >, char, std::char_traits<char>, int>::istream_iterator(std::wistringstream&)'

I think he says that he cannot create an istream_iterator instance using the passed one iss(which is w istringstream instead of istringstream). This is on a Mac using Xcode and GCC 4.2. And AFAIK does not exist wistring_iterator or something like that.

, non-wstring. , wstring, wistringstream vector<wstring>, , .

wstring?

Answer 1

2 3 istream_iterator(), . Visual ++ :

copy(istream_iterator<wstring, wchar_t, std::char_traits<wchar_t> >(iss), // I DO NOT GET THE ERROR HERE
    istream_iterator<wstring, wchar_t, std::char_traits<wchar_t> >(),
    back_inserter< vector<wstring> >(tokens));
