When reverse engineering code Rose gathers information about the classes attributes operations and relationships between the classes to generate the appropriate model elements. Using round-trip engineering you can modify the model and then change the corresponding code or change the code directly and then update the model. Either way round-trip engineering helps keep your code and object model synchronized. In the next chapters we ll take a look at code generation and reverse engineering in more detail for specific languages. 416 Chapter 13 ANSI C and Visual C Code Generation and Reverse Engineering C is one of the most widely used object-oriented languages in the industry. Rational Rose supports integration with C through its code-generation and reverse-engineering capabilities. In this chapter we ll discuss how to generate C code from your Rational Rose model and how to reverse engineer C code into a Rose model. There are three versions of C integration with Rational Rose. First is the C add-in that has been available in Rose since October 1994. It contains a great deal of functionality but can prove difficult to use. The second is an add-in for Microsoft s Visual C . This add-in is simpler to use but will integrate only with Microsoft s Visual C . Rational therefore has introduced the third add-in ANSI C which is an easy-to-use C code-generation and reverse-engineering tool that will work with C tools other than Microsoft s Visual C . In this chapter we will discuss the ANSI C and Visual C add-ins. The original C add-in is still supported but will not be covered here. We ll discuss the code-generation properties that can be set and take a close look at how each Rose model element is implemented in the code. Setting C code-generation properties Mapping Rose elements to C constructs Generating C code from your Rose model Reverse engineering C code into your .
