Method newEnumSet

corpus/java/training/guava/collect/Sets.java:144–149

Returns a new, mutable EnumSet instance containing the given elements in their natural order. This method behaves identically to EnumSet#copyOf(Collection), but also accepts non-Collection iterables and empty iterables.

      Iterable<E> iterable, Class<E> elementType)
