[Soot-list] How to change the return type of an method

[Steven Arzt]

Hi Benedikt,

 

What do you mean by „change the return value”? Do you want to change the implementation of the method to return something else, i.e., change or replace its behavior?

 

Best regards,

  Steven

Hi,

I want to change the return value of the filereader.readline() method.

 

all I have is the following

 

@Override

protected void internalTransform(final Body b, String phaseName, @SuppressWarnings("rawtypes") Map options) {

                                               

            Iterator<Unit> iter = b.getUnits().snapshotIterator();

            while (iter.hasNext()) {

                        Stmt s = (Stmt) iter.next();

                        if (s.containsInvokeExpr()) {

                                   SootMethod method = s.getInvokeExpr().getMethod();

                                   String declaringClass = s.getInvokeExpr().getMethod().getDeclaringClass().getName();

                                   if(declaringClass.equals("java.io.BufferedReader") && method.getName().equals("readLine")) {

                                               //change return value

                                   }

                        }

            }

}

 

can you please tell how to change the value from here

 

Thanks

Benedikt
