Template specialization and inheritance

Question

Suppose I have a template class with a lot of functions and I want to specialize them to change only a few of them and keep the other ones exactly as specified in the base templ

Answer 1

You just have to use two template classes:

template
struct CommonBase
{
  void print1() {cout << "Base::print1" << endl;};
  void print2() {cout << "Base::print2" << endl;};
};

template
struct Base : public CommonBase
{
};

template<>
struct Base : public CommonBase
{
  void print2() {cout << "Base::print2" << endl;};
};

You always use Base, rather than CommonBase.
