Method newEnumSet

output/java_guava/1.4.19/Sets.java:147–151

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)

  public static <E extends Enum<E>> EnumSet<E> newEnumSet(Iterable<E> iterable, Class<E> elementType) {
    EnumSet<E> set = EnumSet.noneOf(elementType);
    Iterables.addAll(set, iterable);
    return set;
  }

  // HashSet
