METHOD AND APPARATUS FOR ROUND-TRIP SOFTWARE ENGINEERING

A method of round-trip engineering source code from a software model, and in particular a method of forward engineering code previously reverse engineered into a software model whereby to generate updated source code without any changes to the code not changed in the model, and without using obtrusive code markers in the source code. Elements from the original source code represented by the model are placed in a meta-model, and compared to a similar meta-model of the software model. Appropriate changes and additions are made in the source code to elements which have been changed in the software model. The rest of the code in the software model remains untouched.
