Parameters:

l - The List that backs the returned Sequence.

Returns:

A new instance of Sequence that is backed by the given List.

Throws:

NullPointerException - If l is null.

newConstantSequence

public static <E> Sequence<E> newConstantSequence(E constant,
                                                  int length)
                                       throws IllegalArgumentException

Returns a new instance of Sequence that is backed by the given constant for the given length.

Parameters:

constant - The constant that backs the returned Sequence.
