Method Detail

from

public static <E> Peekerator<E> from(Iterator<E> delegate)

Wraps a given Iterator as a Peekerator. That peekerator implements the Peekerator.peek() operation by reading ahead (at most) one element from the underlying iterator.

from

public static <E> Peekerator<E> from(ListIterator<E> delegate)

Wraps a given ListIterator as a Peekerator. That peekerator implements the Peekerator.peek() operation by calling ListIterator.next() and immediately ListIterator.previous().

This implementation may perform slightly better than from(Iterator).
