QuestionDeep copy of List<> without knowing specific list type Pin

I have some DTOs that are written to be immutable.
  private List<Transformation> foo;
... [omitted for brevity]
  public List<Transformation> getFoo() {
    List<Transformation> bar = new ArrayList<Transformation>(foo.size());

    for (Transformation listEntry : foo) {
      bar.add(Transformation.of(listEntry));
    }

    return bar;
  }
This works for my current application as I happen to know that the Lists are all ArrayLists.

What if I didn't know that? Is there a way to deep copy the contents of an arbitrary implementation of List without knowing what type that underlying List is?
