[Soot-list] Main entry points

[Eric Bodden]

Hi.

getMainClass() returns *the* unique main-class for your application.
This class is either stated explicitly on the command line
(-main-class YourMainClass) or it is inferred. In the latter case,
Soot just takes the first application class with a main method it can
find.

I think in your case this method will help:

soot.EntryPoints.mainsOfApplicationClasses()

(call "EntryPoints.v().mainsOfApplicationClasses()")

This returns a list of SootMethod's (all main-methods). For each
method you can then retrieve the declaring class using
m.getDeclaringClass().
