C and C++ code generation issues

Edit online

Wrapping code with #ifdef-#endif
If you need to wrap an operation with an #ifdef #endif pair, add a compiler-specific keyword, or add a #pragma directive, you can set the SpecificationProlog, SpecificationEpilog, ImplementationProlog, and ImplementationEpilog properties for the operation.
Generating classes as structs in C++
You can have one or more classes generated as structs,
Code generation for friend classes and functions
You can define friend classes and friend functions in your Rhapsody model, and the appropriate code will be generated.
Generating operation descriptions in implementation files
By default, descriptions for operations are generated only in the specification files. Using the GenerateDescriptionInImplementation and DescriptionInImplementation properties, you can have a descriptive comment generated in the implementation file as well.
Fine-tuning code generated for arguments
You can use the Code pattern field to fine-tune the code that is generated for the arguments of a specific operation or event. If you want to modify the code generated when a given class, type, or event is used as an operation or event argument anywhere in your model, you can set the value of the relevant In, Out, or InOut property at the class, type, or event level.
Fine-tuning code generated for return types
You can use the Code pattern field to fine-tune the code that is generated for the return type of a specific operation. If you want to modify the code that is generated when a given class, type, or event is used as the return type of an operation anywhere in your model, you can set the value of the ReturnType property at the class, type, or event level.
Generating operations for statechart serialization
IBM Engineering Systems Design Rhapsody provides a mechanism for serialization of reactive instances. By setting a number of Rhapsody properties, you can have methods added to the generated code, which you can then use to implement serialization.
