Andromeda typeid library

AMTypeID - unique integral id for an every typeUseful for example for implementing variant types. You may have union of multiple types and tag with stored type.

Usage

Typical usage is very simple...

#include "amtypeid/AMCETypeID.h"
 
uint64_t sw = AMCETypeID<uint64_t>::id();
 
 switch(sw) {
     case AMCETypeID<uint32_t>::id(): FAIL() << "Switch: bad branch selected";break;
     case AMCETypeID<int64_t>::id(): FAIL() << "Switch: bad branch selected";break;
     case AMCETypeID<uint64_t>::id(): ;break;
     case AMCETypeID<char*>::id(): FAIL() << "Switch: bad branch selected";break;
     case AMCETypeID<std::string>::id(): FAIL() << "Switch: bad branch selected";break;
 }

If you dislike long range of hash, you may put its own id by:

namespace AMCore {
     template<> inline constexpr uint64_t AMCETypeID<uint64_t>::id() { return 100;}
     template<> inline constexpr uint64_t AMCETypeID<int64_t>::id() { return 101;}
     template<> inline constexpr uint64_t AMCETypeID<const char*>::id() { return 102;}
     template<> inline constexpr uint64_t AMCETypeID<uint32_t>::id() { return 104;}
  }
