How to create templatized wrapper class in C++

Question

Hello All,

I am invoking a function from many places in the project. Only difference is that one of the parameters is of different data types.

I was asked to create a templatized wrapper class. Could someone help me how to do that?

I am invoking the below function from different places. Here when invoking this function, the second parameter (f_strCallid) might be string, int, unsigned long etc.

std::shared_ptr<CCallListImpl> CCallListImpl::handleCallCollectionEvents(Events f_eCallEvent, const std::string& f_strCallid)
{
shared_ptr<CCallListImpl> l_hCallObj = nullptr;

return l_hCallObj;

}

Hi,

According to the your description, I suggest you could try the following code:

template <typename T>  
std::shared_ptr<CCallListImpl>  
CCallListImpl::handleCallCollectionEvents(Events f_eCallEvent, const T& f_strCallid)  
{  
    shared_ptr<CCallListImpl> l_hObj = nullptr;  
  
    return l_hObj;  
}  

Best Regards,

Jeanine
