- Direct Known Subclasses:
- KeyWalker
- public class DescendantOrSelfWalker
- extends DescendantWalker
Walker for the 'descendant-or-self' 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.

DescendantOrSelfWalker
public DescendantOrSelfWalker(LocPathIterator locPathIterator)
- Construct a DescendantOrSelfWalker using a LocPathIterator.
- Parameters:
locPathIterator
- The location path iterator that 'owns' this walker.
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 DescendantWalker
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 DescendantWalker
