UnmodifiableBigListIterator

public UnmodifiableBigListIterator(ObjectBigListIterator<K> i)

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: java.util.Iterator

Returns true if the iteration has more elements. (In other words, returns true if Iterator.next() would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<K>

Returns:

true if the iteration has more elements

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<K>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

next

public K next()

Description copied from interface: java.util.Iterator

Returns the next element in the iteration.

Specified by:

next in interface Iterator<K>

Returns:

the next element in the iteration

previous

public K previous()

Description copied from interface: BidirectionalIterator

Returns the previous element from the collection.

Specified by:

previous in interface BidirectionalIterator<K>

Returns:

the previous element from the collection.

See Also:

ListIterator.previous()

nextIndex

public long nextIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to next. (Returns list size if the list iterator is at the end of the list.)

Specified by:

nextIndex in interface BigListIterator<K>

Returns:

the index of the element that would be returned by a subsequent call to next, or list size if list iterator is at end of list.

See Also:

ListIterator.nextIndex()

previousIndex

public long previousIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to previous. (Returns -1 if the list iterator is at the beginning of the list.)

Specified by:

previousIndex in interface BigListIterator<K>

Returns:

the index of the element that would be returned by a subsequent call to previous, or -1 if list iterator is at beginning of list.

ListIterator.previousIndex()
