c++ - How to correctly implement a script parsers exception handling -


i'm having little bit of design problem scripting language i'm creating c++ game engine. i'm trying have object named sscript call method load necessary files, , check script file's suffix. have base class called smessage class named serrormessage derives from. here's example code illustrate want do:

sscript::sscript(const std::string& filepath) {     if (load(filepath) == serror(serror::error_codes::error_custom))     {      } }  smessage& sscript::load(const std::string& filepath) {  }

here's header file serror:

class serror : public smessage { public:     enum class error_codes     {         error_custom = 1,         error_loading_script = 2,         error_script_incorrect_suffix = 3,     };      serror(error_codes errorcode);     serror(error_codes errorcode, const std::string& contents);      virtual void message(const std::string& contents);      inline bool operator=(const error_codes errorcode)     {      }  private:     serror() {};      error_codes m_error_code;      void organizestring(const std::string& contents); };

in sscript::sscript() want call load , compare various smessages or serrormessages. tried implementing operator overload, don't think solve problem. i've sort of hit brick wall, , need serious design rethinking. welcomed , thank much!
