STL container as a template parameter [closed]

Answer 1

There are several things wrong with your code, here is a working example:

template class TContainer, class TObject>
class Foobar
{
public:
    explicit Foobar( TContainer> & container )
    :
    container_( container ){}

private:
    TContainer> & container_;
};

int main()
{
    std::vector v;
    Foobar bla( v );
}

The main fault of your codes it that std::vector takes two template arguments. It looks like this template> class vector;. Also, Joachim Pileborg is right about the double pointer issue, IUnknown**. However, you could simplify your code with the following:

template
class Foobar
{
public:
    explicit Foobar( TContainer & container )
    :
    container_( container ){}

private:
    TContainer & container_; // Be careful with reference members
};

int main()
{
    std::vector v;
    Foobar> bla( v ); // C++11 decltype(v) could be used
}
