Field Summary

private java.lang.Object	child
private java.util.List	children
private int	index
private NodeTest	nodeTest
private NodePointer	parent
private int	position
private boolean	reverse

Constructor Summary

JDOMNodeIterator(NodePointer parent, NodeTest nodeTest, boolean reverse, NodePointer startWith)

Method Summary

NodePointer	getNodePointer()
int	getPosition()
private boolean	next()
private boolean	previous() This is actually never invoked during the normal evaluation of xpaths - an iterator is always going forward, never backwards.
boolean	setPosition(int position) Sets the new current position and returns true if there a node at that position.
private boolean	testChild()

Constructor Detail

JDOMNodeIterator

public JDOMNodeIterator(NodePointer parent,
                        NodeTest nodeTest,
                        boolean reverse,
                        NodePointer startWith)

Method Detail

getNodePointer

public NodePointer getNodePointer()

Specified by:

getNodePointer in interface NodeIterator

getPosition

public int getPosition()

Specified by:

getPosition in interface NodeIterator

setPosition

public boolean setPosition(int position)

Description copied from interface: NodeIterator

Sets the new current position and returns true if there a node at that position.

Specified by:

setPosition in interface NodeIterator

previous

private boolean previous()

This is actually never invoked during the normal evaluation of xpaths - an iterator is always going forward, never backwards. So, this is implemented only for completeness and perhaps for those who use these iterators outside of XPath evaluation.

next

private boolean next()

testChild

private boolean testChild()
