Overriding a member variable in C++

Question

I have run into a bit of a tricky problem in some C++ code, which is most easily described using code. I have classes that are something like:

class MyVarBas         


        

Answer 1

I think your mention of templates may be a good option, so something like:

class MyVarBase
{
};

class MyVar : public MyVarBase
{
  int Foo();
};

template  class MyBase
{
public: 
  MyBase(T* v) : m_var(v) {}
  T* GetVar() { return m_var; }

private:
  T* m_var;
};

class MyClass : public MyBase
{
public:
  MyClass(MyVar* v) : MyBase(v) {}
};

However this would depend on what classes you can actually change. Also, the 'MyClass' definition could be redundant, unless it has other members over and above the MyBase class.
