Re: [isugamedev-devel] template string

[Chad A. <ae...@ae...>]

The way I'd do it is:

/* begin C++ */

template<typename T>
class TypeTraits {
public:
  static const char* name() { return "unknown"; }
};

template<>
class TypeTraits<float> {
public:
  static const char* name() { return "float"; }
};

// add more type traits as you need them

template<typename T>
class myclass {
public:
  static const char* getT() { return TypeTraits<T>::name(); }
};

/* end C++ */

I don't know if I remember the exact syntax for partial template specialization, but that should be
close enough.  :)

And no, there isn't an easy way to make it automatically work.  You do have to make new type traits
for new types.
