LinuxQuestions.org - dynamic template class

Hi All, first of all, thanks for all you do, you guys do great work!

I'm trying to make a template class and make it dynamic... I'll explain it better w/ the code:

Code:

template <class Data>

struct node

{

    Data data;

    node *link;

};

That's just a node to a linked list. Now, here's my main function:

Code:

int main()

{

    node<int> *hp = new node<int>;

    return 0;

}

Now for the question... I know this syntax is wrong and won't work:

Code:

node *hp = new node<int>;

but, is there a way to make that work? Basically what I'm asking is how to create a pointer to a template class, but then dynamically change what type of template class it is.

Here's a class example where I would want this to work:

Code:

class llist

{

public:

    void addNode(int mi_dType);

private:

    node *hp;

};



void llist::addNode(int mi_dType)

{

    if (mi_dType == 1)

        hp = new node<int>;

    else

        hp = new node<string>;

}
