How to Reverse Engineer Simulink files using JAVA API in Rational Rhapsody

Question & Answer

Question

How do you Reverse Engineer Simulink (.m) files using JAVA API in IBM Rational Rhapsody?

Cause

You would like to use Java Application Programming Interfaces [API] code to automate the manual task to be performed with in Rational Rhapsody or to achieve something that is not possible through the Rhapsody GUI.

Answer

In order to Reverse Engineer Simulink (.m) files using JAVA API in IBM Rational Rhapsody, you can use the below code as reference:
