Re: [Boost-users] Unique parameter values for interfaces

6 May 2009


      ...
template<typename S, *int N*>
struct ParameterValue
{
  ParameterValue(S value_) : value(value_) {}
  S value
};
typedef ParameterValue<std::string, *0*>   ConfigName;
typedef ParameterValue<std::string, *1*>   PathName;
You could use inheritance the use of numeric tagging.

template <typename T>
struct Param {
  T value;
};

struct ConfigName : Param<string> { };
struct PathName : Param<string> { };
