Question

I have a template class in C++ (somewhat simplified):

template<typename T>
struct C
{
  T member;
  void set(const &T x) { member = x; }
  void set(int x) { member = x; }
};

As you can see the set() function can be called either with the type T, or with an int. This works fine unless T is an int, in which case I get an ambiguous conversion error. I understand why this is happening, but is there any way to implement what I want?

Answer 1

One way around this would be to provide a specialisation of the template for int that only has one set function. Otherwise you might want to have a look at the Boost libraries if something like enable_if in their template meta programming code would allow you to turn on the function set(int x)only when T is not of type int.
