Question

I have the following template method declared in my interface:

class IObjectFactory
{
public:
    virtual ~IObjectFactory() { }

    virtual int32_t Init() = 0;
    virtual bool Destroy() = 0;
    virtual bool Start() = 0;
    virtual bool Stop() = 0;
    virtual bool isRunning() = 0;
    virtual void Tick() = 0;

    template <class T>
    Object<T> CreateObject(T);
};

I am not sure how the call looks like though. I thought the following would be enough, where mObjFactory is an implementation of previously mentioned virtual class;

inline void AllocateWithMemPoolAux() {  mObjFactory->CreateObject<TestClass1>(); }

The error I get is “No instance of function template matches the argument list”
What does the proper function call look like?

(also – as a sidenote, is it okay to declare a template method in an interface and demand the user implement it? as you cannot declare it virtual)

Thanks

Answer 1

notice:

template <class T>
Object<T> CreateObject(T);

did you mean

template <class T>
Object<T> CreateObject();

?
