Gemme et objekt i en vektor

Hej

Jeg har et problem som jeg har stirret mig blindt på. Jeg har denne klasse, fileBuf, som faktisk bare pusher en fileStream på en vector, men den giver rimlig mange fejl, eller faktisk bare en stor.

fileBuf.cpp
class fileBuf
{
public:
  void updateFile(fileStream);

private:
  vector<fileStream> buffer;
};

void fileBuf::updateFile(fileStream f)
{

  buffer.push_back(f);

}

og min fileStream.cpp
class fileStream
{
public:
  void setFile(string);
  string returnFile();
  ifstream & returnIfStream();

private:
  ifstream f;
};

using namespace std;
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include "fileHandling.h"
#include "FileBuffer.cpp"

ifstream & fileStream::returnIfStream()
{
  return f;
}

void  fileStream::setFile(string g)
{

  f.open(g.c_str());

}


string fileStream::returnFile()
{

  string s;
  string fullFilled;

  if(!f)
    {

      fullFilled = "Filen kunne ikke aabnes";

    }else
      {

        while(getline(f,s))
          fullFilled += s;

      }

  return fullFilled;

}


int main()
{
  fileStream ny;
  ny.setFile("ha.txt");
  cout << ny.returnFile() << endl;
  return 0;
}

Fejlen jeg får er

Jeg tror at det er fordi jeg har en ifstream i min fileStream og det måske er det som ødelægger det lidt, men jeg ved det ikke. Fejlen forkommer ihvertfald der hvor jeg prøver at pushe min fileStream i min vector i fileBuffer klassen.

Håber i vil hjælpe lidt?

Mvh.
