Soot will automatically load all methods of all classes on your process-dir for you. These classes are also automatically set as application classes. For your analysis or transformation, you register a BodyTransformer or a SceneTransformer and then call Soot’s main method. Soot will make sure that all application classes are properly loaded before invoking your custom transformers.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Soot can be thought of as a compiler pipeline. You put your program in and register different actions that shall be done to it. In Soot, these actions are organized in packs and phases (see <a href="http://www.bodden.de/2008/11/26/soot-packs/">http://www.bodden.de/2008/11/26/soot-packs/</a>).

Loading a method body for instance only works if the method can have a body at all. If it’s, for instance, native or abstract and you try to load its body, you’ll get the exception you have reported. That’s what I meant with “inner workings”: Normally, the framework does all these checks and gives you a valid Scene to work with inside your transformers.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Best regards,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> Steven<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>Von:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Jason Ott [mailto:jott002@ucr.edu] <br><b>Gesendet:</b> Freitag, 24.
