public class PrecedingSiblingWalker
extends ReverseAxesWalker

Walker for the 'preceding-sibling' axes.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Constructor Detail

PrecedingSiblingWalker

public PrecedingSiblingWalker(LocPathIterator locPathIterator)

Construct a PrecedingSiblingWalker using a LocPathIterator.

Parameters:: locPathIterator - The location path iterator that 'owns' this walker.

Method Detail

nextSibling

public org.w3c.dom.Node nextSibling()

Moves the TreeWalker to the next sibling of the current node, and returns the new node. If the current node has no visible next sibling, returns null , and retains the current node.

Returns:: The new node, or null if the current node has no next sibling in the TreeWalker's logical view.
Overrides:: nextSibling in class AxesWalker

getLevelMax

protected int getLevelMax()

Tell what's the maximum level this axes can descend to.

Returns:: An estimation of the maximum level this axes can descend to.
Overrides:: getLevelMax in class AxesWalker
