Partial template specialization on a class
- by Jonathan Swinney
I'm looking for a better way to this. I have a chunk of code that needs to handle several different objects that contain different types. The structure that I have looks like this:
class Base
{
// some generic methods
}
template <typename T> class TypedBase : public Base
{
// common code with template specialization
private:
std::map<int,T> mapContainingSomeDataOfTypeT;
}
template <> class TypedBase<std::string> : public Base
{
// common code with template specialization
public:
void set( std::string ); // functions not needed for other types
std::string get();
private:
std::map<int,std::string> mapContainingSomeDataOfTypeT;
// some data not needed for other types
}
Now I need to add some additional functionality that only applies to one of the derivative classes. Specifically the std::string derivation, but the type doesn't actually matter. The class is big enough that I would prefer not copy the whole thing simply to specialize a small part of it. I need to add a couple of functions (and accessor and modifier) and modify the body of several of the other functions. Is there a better way to accomplish this?
