code: @GwtIncompatible // Array.newArray(Class, int)
    public final E[] toArray(Class<E> type) {
      return Iterables.toArray(getDelegate(), type);
    }
docs: Returns an array containing all of the elements from this fluent iterable in iteration order.
  
  <p><b>{@code Stream} equivalent:</b> if an object array is acceptable, use {@code
  stream.toArray()}; if {@code type} is a class literal such as {@code MyType.class}, use {@code
  stream.toArray(MyType[]::new)}. Otherwise use {@code stream.toArray( len -> (E[])
  Array.newInstance(type, len))}.
  
  @param type the type of the elements
  @return a newly-allocated array into which all the elements of this fluent iterable have been
  copied
