public class FollowingWalker
extends AxesWalker

Walker for the 'following' 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.

Field Detail

m_ancestors

protected transient java.util.Stack m_ancestors
Stack of ancestors of the root/context node.
Constructor Detail

FollowingWalker

public FollowingWalker(LocPathIterator locPathIterator)
Construct a FollowingWalker using a LocPathIterator.

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

setRoot

public void setRoot(org.w3c.dom.Node root)
Set the root node of the TreeWalker.

Parameters:
root - The context node of this step.
Overrides:
setRoot in class AxesWalker

parentNode

public org.w3c.dom.Node parentNode()
Moves to and returns the closest visible ancestor node of the current node. If the search for parentNode attempts to step upward from the TreeWalker's root node, or if it fails to find a visible ancestor node, this method retains the current position and returns null.

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

firstChild

public org.w3c.dom.Node firstChild()
Moves the TreeWalker to the first visible child of the current node, and returns the new node. If the current node has no visible children, returns null , and retains the current node.

Returns:
The new node, or null if the current node has no visible children in the TreeWalker's logical view.
Overrides:
firstChild in class AxesWalker

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:
Short.MAX_VALUE.
Overrides:
getLevelMax in class AxesWalker
