Thread: Problem in understanding the logic

Hi,


i have problem in understanding the logic behind function declaration and definitions which prevents me from writting the function outside the class scope:

so this works

Code:

template <typename Tkey, typename Tvalue>
class CPS_Index {

private:
	Tkey key;
	Tvalue value;
	
	
template<typename T1>
void print(T1 x){
   cout << x;
};

public:

	CPS_Index(Tkey k=0 ,Tvalue v=0);


};


template <typename Tkey, typename Tvalue>
CPS_Index<Tkey,Tvalue>::CPS_Index(Tkey k ,Tvalue v) : key(k), value(v)
{
		print("Constructed!\n");
}

but i would like to write my function print() outside the class. something like :

Code:

template <typename Tkey, typename Tvalue>
class CPS_Index {

private:
	Tkey key;
	Tvalue value;
	
	template <typename T1>
        void print(T1 x);

public:

	CPS_Index(Tkey k=0 ,Tvalue v=0);


};


template <typename Tkey, typename Tvalue>
CPS_Index<Tkey,Tvalue>::CPS_Index(Tkey k ,Tvalue v) : key(k), value(v)
{
		print("Constructed!\n");
}

template <typename Tkey, typename Tvalue>
void CPS_Index<Tkey,Tvalue>::print( T1 x)
{
	cout << x;
}

This of course does not work since T1 is not recognized. How to make it work?

thank you !
