[Soot-list] soot can not output call graph

[Alexandre Bartel]

Hi ConlyXia,

You need to create a Scene transformer and run Soot in whole-program
mode to retrieve the call graph.
See http://www.bodden.de/2008/11/26/soot-packs/

Below is a code snippet to print the methods called in the main method:

public class MyPack {
public static void main(String[] args) {
  PackManager.v().getPack("wjtp").add(
      new Transform("wjtp.myTransform", new SceneTransformer() {
        protected void internalTransform(String phaseName,
            Map options) {
          System.out.println("--- start");
          CallGraph cg = Scene.v().getCallGraph();
          SootMethod entryPoint = Scene.v().getEntryPoints().get(0); // main by default
          Iterator<Edge> it = cg.edgesOutOf(entryPoint);
          while(it.hasNext()) {
            Edge e = it.next();
            System.out.println("edge out of main: "+ e.getTgt());
          }
          System.out.println("--- end");
        }
      }));
  soot.Main.main(args);
}
}

Running the above code on the following small example

public class Main {

  public static void main(String[] args) {
    foo();
  }

  public static void foo() {
    bar();
  }

  public static void bar() {
  }

}

should give the following output:

[...]
--- start
edge out of main: <java.lang.Object: void <clinit>()>
edge out of main: <Main: void foo()>
--- end
[...]

Best Regards,
Alexandre
