C++ Code Generated for XSD Types

---

For C++, a class definition is generated for each XSD type. This class is derived from either the OSRTBaseType run-time class or from a descendent of this class. The class may contain a constructor for initialization of member variables and a destructor to free dynamic memory held by the class. Method declarations will also be generated instead of C function prototypes for encoding, decoding, printing, and generation of test data. For some types, additional helper methods may also be declared (for example, enumerated type definitions contain a toString method declaration).

A sample section from a C++ header file corresponding to the XSD Name type defined above is as follows:

/**************************************************************/
 
/*                                                            */
 
/*  Name                                                      */
 
/*                                                            */
 
/**************************************************************/
 

 
class EXTERN Name : public OSXSDComplexType {
 
public:
 
   OSXMLStringClass givenName;
 
   OSXMLStringClass initial;
 
   OSXMLStringClass familyName;
 

 
   Name ();
 
   Name (const Name&);
 

 
   virtual int encodeXML (OSRTMessageBufferIF& msgbuf, 
 
      const OSUTF8CHAR* elemName, const OSUTF8CHAR* nsPrefix);
 

 
   virtual int decodeXML (OSCTXT* pctxt);
 

 
   static int validateXML (OSCTXT* pctxt);
 

 
   virtual void print (const char* name);
 

 
   OSRTBaseType* clone () const {
 
      return new Name (*this);
 
   }
 

 
   Name& operator= (const Name&);
 

 
} ;
 

 

If you compare this to what was generated for C above, you will notice that all of the items are now encapsulated within a class definition. This includes the element declarations as well as the functions which are now methods in the class.
