Please share your thoughts on Member Function Templates

Hi All C++ Experts
Can anybody share some of your thoughts in Member Function Templates
implementation.Can you also give some example on it

Best Regards
Raj

What exactly would you like to know? Here is an example:

class ConvertibleToAPointer {
// ...
public:
template<class T> operator T*();
};

Here is another example:

class CanWorkOnAPointer {
// ...
public:
template<class T> void workOn(T*);
};

As to thoughts, here is one: unfortunately some compilers don't support
those well, as I discovered today. But then again, they just have some
bad template support in general...

Hi
Victor you are correct , i was having code like this
class ConvertibleToAPointer {
// ...
public:
template<class T> operator T*();
};


void fun(char *x)
{}

main()
{
ConvertibleToAPointer obj;
fun(obj);

}

so this code is not compiling . i think my compiler is not supporting
member template function.

Is there any get around way of doing this.

regards rajendra

Try to specify the type explicitly:

class ConvertibleToAPointer {
public:
template<class T> T* convert2ptr() { return 0; }
};

void fun(char* x) {}

int main()
{
ConvertibleToAPointer obj;
fun(obj.convert2ptr<char>());
}

If your compiler has other quirks, you might consider posting questions
about them to that compiler's newsgroup (if it exists, of course).

Victor, Rajan is using VC6.

Rajan, As I said earlier, VC6 is known to have issues with template
code, especially member function templates. You need to upgrade your
compiler.
