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.
