[omniORB] Getting something out of an exception

[Len Holgate (Mail List Account)]

Or, something like this works, though I guess it's a bit of a brute force
approach...

#ifndef __OMNIORB_USEREXCEPTION_H__
#include <omniORB3/userexception.h>
#endif


#define DoThis(_ex)                                                  \
   if (CORBA::_ex::_narrow(const_cast<CORBA::Exception *>(&e)))      \
   {                                                                 \
      return "CORBA::" #_ex;                                         \
   }                                                                 \

static std::string GetNameFromCORBAException(const CORBA::Exception &e)
{
   OMNIORB_FOR_EACH_SYS_EXCEPTION(DoThis)

   if (CORBA::UserException::_narrow(const_cast<CORBA::Exception *>(&e)))
   {
      return "CORBA::UserException";
   }

   return "Unrecognised CORBA::Exception!";
}
