[Soot-list] using DeclaresMethod in SootClass

[Nomair A. Naeem]

Hey Guys,
   A question for the Soot gurus:

Suppose a SootClass declares a method
       foo(List)

Now I need to be able to check whether it declares a Method
      foo(ArrayList)

The declaresMethod method should return true in the case the
SootClass declares a method where the paramtypes are super types of the
types i am trying to match e.g. ArrayList is a subType of List.

How do i do this.

An attempt was as follows:
    List argList = new ArrayList();
    argList.add(RefType.v("java.util.ArrayList");

   testSootClass.declaresMethod("foo",argList);

The declaresMethod returns false.

Any suggestions.
