c – 如何在子类中重载模板化函数(专用)？

#ifndef BASE_CLASS
#define BASE_CLASS

#include <iostream>

using namespace std;

struct Type1
{
};

struct Type2
{
};

class baseClass
{
    public:
    template<class Type>
    void doStuff(Type & t)
        {
        templateFunction(t);  
        }

    template<class Type>
    void templateFunction(Type & t);
};

template<class Type>
void baseClass::templateFunction(Type & t)
{
    cout << "This is the generic function!" << endl;
}

template<>
void baseClass::templateFunction(Type1 & t)
{
    cout << "This is the specialized function: - Type1" << endl;
}
#endif

我还有一个继承自“baseClass”的子类.但是,子类需要不同的专业化功能.

#ifndef CHILD_CLASS
#define CHILD_CLASS

#include "BaseClass.h"

class ChildClass : public baseClass
{
    public:

};

template<>
void ChildClass::templateFunction(Type1 & t)
{
    cout << "We overloaded the specialized template function for type 1!" << endl;
}

#endif

以上不编译：

ChildClass.h：13：错误：没有在aChildClass中声明的成员函数atemplateFunction
ChildClass.h：13：错误：函数声明无效

如果我将“重载”功能更改为：

template<>
void baseClass::templateFunction(Type1 & t)
{
    cout << "We overloaded the specialized template function for type 1!" << endl;
}

我明白了：
ChildClass.h：13：错误：重新定义avoidbaseClass:: templateFunction(Type&)[with Type = Type1]a
BaseClass.h：36：错误：avoidbaseClass:: templateFunction(Type&)[with Type = Type1]a在此声明

如何正确地重载子类中的专用模板函数？

供参考,主要：

#include "BaseClass.h"
#include "ChildClass.h"

int main()
{
    Type1 first;
    Type2 second;

    baseClass theBaseClass;
    ChildClass theChildClass;


    theBaseClass.doStuff(first);
    theBaseClass.doStuff(second);

    theChildClass.doStuff(first);
    theChildClass.doStuff(second);

    return 0;
}

根据以下建议：Kerrek SB,我已将ChildClass更改为：

#ifndef CHILD_CLASS
#define CHILD_CLASS

#include "BaseClass.h"
class ChildClass : public baseClass
{
    public:
    template<class Type>
    void templateFunction(Type & t);
};

template<>
void ChildClass::templateFunction(Type1 & t)
{
    cout << "We overloaded the specialized template function for type 1!" << endl;
}

#endif

输出：

This is the specialized function: - Type1
This is the generic function!
This is the specialized function: - Type1
This is the generic function!

我希望：

This is the specialized function: - Type1
This is the generic function!
We overloaded the specialized template function for type 1!
This is the generic function!

所以这仍然不起作用.
