public static class ImmutableSet.Builder<E> extends ImmutableCollection.Builder<E>
ImmutableSet instances. Example: static final ImmutableSet<Color> GOOGLE_COLORS =
ImmutableSet.<Color>builder()
.addAll(WEBSAFE_COLORS)
.add(new Color(0, 191, 255))
.build();
Building does not change the state of the builder, so it is still possible to add more elements and to build again.
