Classdesc modification to parse a user supplied C++ model

Classdesc is used to generate an action definition write_objc that is a program generator outputting the Objective C definitions representing the C++ object. Classdesc takes a flag -objc to enable the right sort of output. The An example of the Classdesc output is shown in Figure 10.

Figure 10: An example of Classdesc output

The output from the Classdesc is stored in the .cd file, which consists mostly of writeobjc statements (or actions). These overloaded writeobjc statements will recursive descend the class definition performing the “translation" operation on each primitive data type making-up the class. The definitions of writeobjc actions on all primitive data type, including member function type, are defined in the writeobjc_base.h file (Classdesc base action definition file).
