want comparison on Iterable-s #659

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The method Iterables.elementsEqual essentially transforms method equals on T 
into equals on Iterable<T>. I recently needed to essentially turn a 
Comparator<T> into a Comparator<Iterable<T>>. This would have been OK:

  int Iterables.compareElements(Comparator<T>, Iterable<T>, Iterable<T>)

Fortunately, Guava already has a much nicer way of doing this!

  Ordering<Iterable<T>> o = Ordering.from(comparator).lexicographical();
