specialize only (a part of) one method of a template class
问题 If I have a template class template<typename T> class C { public: void method1() { ... } void method2() { ... } std::string method3(T &t) { // ... std::string s = t.SerializeToString(); // ... return s; } // ... }; and I want to specialize it for T = std::string but only changing method3(T&) (keeping all other methods), or even better, only that part of method3, which for T = std::string would simply become std::string s = t; , with minimum impact on current code (less repetition of methods
