Method copyOf

output/java_guava/1.4.17/ImmutableList.java:230–235

Returns an immutable list containing the given elements, in order. If elements is a Collection, this method behaves exactly as #copyOf(Collection); otherwise, it behaves exactly as copyOf(elements.iterator(). @throws NullPointerException if any of elements is

(Iterable<? extends E> elements)

  public static <E> ImmutableList<E> copyOf(Iterable<? extends E> elements) {
    checkNotNull(elements); // TODO(kevinb): is this here only for GWT?
    return (elements instanceof Collection)
      ? copyOf((Collection<? extends E>) elements)
      : copyOf(elements.iterator());
  }
