For C++, a class definition is generated for each WSDL Operation onput/output/fault type defined in binding. This class is derived from the OSXSDComplexTyperun-time 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.

A sample section from sample CalcWSDL C++ header file is as follows:
