+--org.apache.commons.collections.list.AbstractLinkedList.LinkedListIterator
   |
   +--org.apache.commons.collections.list.CursorableLinkedList.Cursor
Enclosing Class:


public static class CursorableLinkedList.Cursor
extends
AbstractLinkedList.LinkedListIterator

An extended ListIterator that allows concurrent changes to the underlying list.

Constructor Summary

Cursor(CursorableLinkedList parent, int index)

Constructs a new cursor.

Method Summary

void

add(Object obj)

Adds an object to the list.

void

checkModCount()

Override superclass modCount check, and replace it with our valid flag.

void

close()

Mark this cursor as no longer being needed.

int

nextIndex()

Gets the index of the next element to be returned.

void

nodeChanged(AbstractLinkedList.Node node)

Handle event from the list when a node has changed.

void

nodeInserted(AbstractLinkedList.Node node)

Handle event from the list when a node has been added.

void

nodeRemoved(AbstractLinkedList.Node node)

Handle event from the list when a node has been removed.

Constructor Details

Cursor

protected Cursor(CursorableLinkedList parent, int index)

Constructs a new cursor.

Parameters:
parent - the index to start from
index

Method Details

add

public void add(Object obj)

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

Parameters:
obj - the object to add

checkModCount

protected void checkModCount()

Override superclass modCount check, and replace it with our valid flag.


close

public void close()

Mark this cursor as no longer being needed. Any resources associated with this cursor are immediately released. In previous versions of this class, it was mandatory to close all cursor objects to avoid memory leaks. It is no longer necessary to call this close method; an instance of this class can now be treated exactly like a normal iterator.


nextIndex

public int nextIndex()

Gets the index of the next element to be returned.

Returns:
the next index

nodeChanged

protected void nodeChanged(AbstractLinkedList.Node node)

Handle event from the list when a node has changed.

Parameters:
node - the node that changed

nodeInserted

protected void nodeInserted(AbstractLinkedList.Node node)

Handle event from the list when a node has been added.

Parameters:
node - the node that was added

nodeRemoved

protected void nodeRemoved(AbstractLinkedList.Node node)

Handle event from the list when a node has been removed.

Parameters:
node - the node that was removed
