Field Details

EMPTY_BIG_LIST_ITERATOR

public static final ObjectBigListIterators.EmptyBigListIterator EMPTY_BIG_LIST_ITERATOR

An empty iterator (immutable). It is serializable and cloneable.

The class of this objects represent an abstract empty iterator that can iterate as a type-specific (list) iterator.

Method Details

singleton

public static <K> ObjectBigListIterator<K> singleton(K element)

Returns an iterator that iterates just over the given element.

Parameters:

element - the only element to be returned by a type-specific list iterator.

Returns:

an iterator that iterates just over element.

unmodifiable

public static <K> ObjectBigListIterator<K> unmodifiable(ObjectBigListIterator<? extends K> i)

Returns an unmodifiable list iterator backed by the specified list iterator.

Parameters:

i - the list iterator to be wrapped in an unmodifiable list iterator.

Returns:

an unmodifiable view of the specified list iterator.

asBigListIterator

public static <K> ObjectBigListIterator<K> asBigListIterator(ObjectListIterator<K> i)

Returns a big-list iterator backed by the specified list iterator.

Parameters:

i - the list iterator to adapted to the big-list-iterator interface.

Returns:

a big-list iterator backed by the specified list iterator.
