Field Detail

sub

protected final AbstractLinkedList.LinkedSubList<E> sub

The parent list

Constructor Detail

SubCursor

protected SubCursor(AbstractLinkedList.LinkedSubList<E> sub,
                    int index)

Constructs a new cursor.

Parameters:

sub - the sub list

index - the index to start from

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<E>

Specified by:

hasNext in interface ListIterator<E>

Overrides:

hasNext in class AbstractLinkedList.LinkedListIterator<E>

hasPrevious

public boolean hasPrevious()

Description copied from interface: OrderedIterator

Checks to see if there is a previous element that can be iterated to.

Specified by:

hasPrevious in interface ListIterator<E>

Specified by:

hasPrevious in interface OrderedIterator<E>

Overrides:

hasPrevious in class AbstractLinkedList.LinkedListIterator<E>

Returns:

true if the iterator has a previous element

nextIndex

public int nextIndex()

Description copied from class: CursorableLinkedList.Cursor

Gets the index of the next element to be returned.

Specified by:

nextIndex in interface ListIterator<E>

Overrides:

nextIndex in class CursorableLinkedList.Cursor<E>

Returns:

the next index

add

public void add(E obj)

Description copied from class: CursorableLinkedList.Cursor

Adds an object to the list. The object added here will be the new 'previous' in the iterator.

Specified by:

add in interface ListIterator<E>

Overrides:

add in class CursorableLinkedList.Cursor<E>

Parameters:

obj - the object to add

remove

public void remove()

Description copied from class: CursorableLinkedList.Cursor

Removes the item last returned by this iterator.

There may have been subsequent alterations to the list since you obtained this item, however you can still remove it. You can even remove it if the item is no longer in the main list. However, you can't call this method on the same iterator more than once without calling next() or previous().

Specified by:

remove in interface Iterator<E>

Specified by:

remove in interface ListIterator<E>

Overrides:

remove in class CursorableLinkedList.Cursor<E>
