Method Detail

of

public static <E> Ord<E> of(int n,
                            E e)

Creates an Ord.

zip

public static <E> Iterable<Ord<E>> zip(Iterable<? extends E> iterable)

Creates an iterable of Ords over an iterable.

zip

public static <E> Iterator<Ord<E>> zip(Iterator<? extends E> iterator)

Creates an iterator of Ords over an iterator.

zip

public static <E> List<Ord<E>> zip(E[] elements)

Returns a numbered list based on an array.

zip
