[Soot-list] Soot-list Digest, Vol 89, Issue 23

[Pauline Anthonysamy]

Many thanks to Cheng and Quentin!!

I bypassed the exception. My mistake was passing the class name within 
Options.v().parse().

Below is a working example for future noobs!

public class CallGraphExample {
     public static void main(String[] args) {

         // PackManager manages the packs containing the various phases 
and their options
         PackManager.v().getPack("wjtp")
         .add(new Transform("wjtp.myTransform", new SceneTransformer() {

             @Override
             protected void internalTransform(String phaseName, Map 
options) {
                 System.out.println("\n\n -----> 5 \n\n");

                 CHATransformer.v().transform();
                 SootMethod src = 
Scene.v().getMainClass().getMethodByName("doStuff");
                 System.out.println("\n\n -----> 6 \n\n");

                 CallGraph cg = Scene.v().getCallGraph();
                 System.out.println("\n\n -----> 7 \n\n");

                 Iterator<MethodOrMethodContext> targets = new 
Targets(cg.edgesOutOf(src));
                     while (targets.hasNext()) {
                         System.out.println("\n\n -----> 8 \n\n");

                         SootMethod tgt = (SootMethod)targets.next();
                         System.out.println("\n\n -----> 9 \n\n");

                         System.out.println(src + " may call " + tgt);
                     }
             }

         }));


         System.out.println("\n\n -----> 1 \n\n");

         Options.v().parse(new String[] {"-w"});
         SootClass a = Scene.v().forceResolve("test.CallGraphs", 
SootClass.BODIES);
         a.setApplicationClass();
         Scene.v().loadNecessaryClasses();
         SootMethod m = a.getMethodByName("doStuff");

         System.out.println("\n\n -----> 2 \n\n");

         ArrayList<SootMethod> entryPoints = new ArrayList<SootMethod>();
         entryPoints.add(m);

         System.out.println("\n\n -----> 3 \n\n");

         System.out.println("STUFF: " + entryPoints.get(0));


         Scene.v().setEntryPoints(entryPoints);

         System.out.println("\n\n -----> 4 \n\n");

         PackManager.v().runPacks(); //soot.Main.main(args);
         }
}
