How do I check my template class is of a specific classtype?

Question

In my template-ized function, I\'m trying to check the type T is of a specific type. How would I do that?

p/s I knew the template specification way but I don\'t want

Answer 1

hmm because I had a large portion of same code until the 'specification' part.

You can use overloading, but if a large part of the code would work for any type, you might consider extracting the differing part into a separate function and overload that.

template 
void specific(const T&);

void specific(const std::string&);

template 
void something(const T& t)
{
    //code that works on all types
    specific(t);
    //more code that works on all types
}
