相关疑难解决方法(0)

我有以下问题:

class Base
{
};

class Derived : public Base
{
};

class Different
{
};

class X
{
public:
  template <typename T>
  static const char *func(T *data)
  {
    // Do something generic...
    return "Generic";
  }

  static const char *func(Base *data)
  {
    // Do something specific...
    return "Specific";
  }
};

如果我现在这样做

Derived derived;
Different different;
std::cout << "Derived: " << X::func(&derived) << std::endl;
std::cout << "Different: " << X::func(&different) << std::endl;

我明白了

Derived: Generic
Different: Generic

但我想要的是,对于从Base派生的所有类,调用特定方法.所以结果应该是:

Derived: Specific
Different: …
