So you have a C++ template class, but you want to specifiy a member function for a particular type of data:
1 // A template class called Image: 2 template <class T> 3 class Image { 4 public: 5 // ======================== 6 // CONSTRUCTOR & DESTRUCTOR 7 Image() : width(0), height(0), data(NULL) {} 8 Image(const Image &image) : data(NULL) { 9 copy_helper(image); } 10 const Image& operator=(const Image &image) { 11 if (this != &image) 12 copy_helper(image); 13 return *this; } 14 ~Image() { 15 delete [] data; 16 } 17 bool Load(const std::string &filename); 18 }; 19 20 // But you want to specify a function for a particular type: 21 template <> // notice this is an empty arrow bracket 22 bool Image<Offset>::Load(const std::string &filename) { // Offset is a class, you can specify Offset so you don‘t put a T in the arrow bracket 23 ... // sth here 24 }
A template class that has a function for specific type
