@Override
  public int getColumn() {
    return column;
  }
An anticipated interaction between the SUT and one or more mock objects.

<p>An instance of this class is confined to a {@link MockController} and all method calls
should be done in {@code synchronized} blocks that synchronize on that Mock controller to
ensure proper interaction matching and invocation counting. Due to that this class is not
thread-safe.
