[Soot-list] process-dir, main-class, entry points and call graph

[Eric Bodden]

Hi Jiangfan.

-main-class and -process-dir are completely different things.

-mail-class is only meaningful when whole-program mode (-w) is
enabled. In this case, -main-class denotes the main class that is used
as the starting point of the call graph. Soot will construct a call
graph for all methods reachable from the main method of this main
class, and will load all bodies of those methods.

-app, on the other hand, is really just meaningful when *not* running
in -w mode. In this case, -app has an impact on which methods Soot
loads bodies for and therefore passes to the registered
BodyTransformers. Without -app, Soot only loads bodies for classes
explicitly mentioned on the command line (and in -process-dir), with
-app Soot also loads bodies for all classes transitively referenced by
the former.

-process-dir is just a quick way of making all classes in a directory
"application classes", i.e. load and process their bodies. Again, this
is only useful when not in -w mode.
