 /**

  * iteration order. Does not permit null keys or values.
  *
  * <p>Unlike {@link Multimaps#unmodifiableListMultimap(ListMultimap)}, which is

  * {@code ImmutableListMultimap} contains its own data and will <i>never</i>
  * change. {@code ImmutableListMultimap} is convenient for

  *
  * <p><b>Note:</b> Although this class is not final, it cannot be subclassed as
  * it has no public or protected constructors. Thus, instances of this class
  * are guaranteed to be immutable.
