Java Round-Trip vs Instant Reverse

General Questions/Discussions
1

Hello,
I’m evaluating VP-UML professional. I have several libraries that I’d like to reverse into class diagrams. I also have a NetBeans project that uses these libraries that I’d like to manage with Round-Trip engineering. How should I proceed?

It’s not clear to me what the differences are between the Instant Reverse/Generator options and the Java Round-Trip options.

Hi Bruce,

Thanks for your post. Instant Reverse/Generator is one-off engineering, which means it will overwrite your models/code every time you run it. But for Java round-trip engineering, it only updates the changes in code to models, or vice versa.

e.g. if you have code containing implementation of operations, you reverse it to VP-UML and perform further modeling on the reversed class model. If you generate code from the model to the original code, it will completely overwrite your original code, i.e. implementation will lose.

Hope this is clear. If there is any further inquiry, please let me know.

Best regards,
Lilian Wong
