Re: how to implement MAP<std::string,TYPE>

  If all these classes inherit from the same base class, you can use a
map from string to ptrs to representative objects of each class. This
can serve as a good replacement for your need of type introspection.

class CBase
{
......
  // to return results of default constructor
  virtual CBase * new_obj() = 0;
   // add more prototypes for other constructors
 ......
  virtual const char *name() = 0; // type name
};

class CA : public CBase
{
 ...
};

class CB : public CBase
{
......
};

std::map<std::string, CBase *> name_to_type;

  After filling the map, you would be able to use these objects, call
their common methods, create objects of the same type, query the name
of their type etc.
