data member of a class template, or a member function template. The complete definition must appear before the explicit instantiation of a class template, a member class of a class template, or a member class template, unless an explicit specialization with the same template arguments appeared ...
In member function of class, if type of parameter is the same class or base class, parameter’s private or protected data member can be visited directly in member function, else it is not allowed. Void Dragon::memberfunction( const Dragon & ll); data member of Dragon can be visited direc...
A template has only one type, but a specialization is needed for pointer, reference, pointer to member, or function pointer types. The specialization itself is still a template on the type pointed to or referenced. Example 复制 // partial_specialization_of_class_templates.cpp template <class ...
template<> struct Producer<void> { void Produce() { Log("Producing void!"); // I want to call Producer<T>::Produce() // as if this specialization didn't exist Producer::Produce(); // this doesn't work } }; The idea is that you want the specializedProducer<void>::Produce()metho...
// template_instantiation2.cpp template<class T> class X { }; // Explicit specialization of X with 'int' template<> class X<int> { }; int main() { } Explicit specialization without template<> will produce an error. Versions of Visual C++ before Visual C++ .NET 2003 accepted this synt...
