Since there is no common base class between 00051 * input and output CDRs, the assingment code must be duplicated. 00052 */ 00053 00054 class TAO_Codeset_Export TAO_Codeset_Translator_Factory : 00055 public TAO_Codeset_Translator_Base, 00056 public ACE_Service_Object 00057 { 00058 public: 00059 TAO_Codeset_Translator_Factory (); 00060 virtual ~TAO_Codeset_Translator_Factory (); 00061 virtual int init (int argc, ACE_TCHAR *argv[]); 00062 00063 protected: 00064 /// Assign the translator to the supplied input CDR.
