Class DTMAxisIterNodeList

  extended by org.apache.xml.dtm.ref.DTMNodeListBase
      extended by org.apache.xml.dtm.ref.DTMAxisIterNodeList
All Implemented Interfaces:

public class DTMAxisIterNodeList
extends DTMNodeListBase

DTMAxisNodeList gives us an implementation of the DOM's NodeList interface wrapped around a DTM Iterator. The author considers this something of an abominations, since NodeList was not intended to be a general purpose "list of nodes" API and is generally considered by the DOM WG to have be a mistake... but I'm told that some of the XPath/XSLT folks say they must have this solution. Please note that this is not necessarily equivlaent to a DOM NodeList operating over the same document. In particular:

State: In progress!!

                           DTMAxisIterator dtmAxisIterator)
Public constructor: Wrap a DTMNodeList around an existing and preconfigured DTMAxisIterator

Method Detail


public DTMAxisIterator getDTMAxisIterator()
Access the wrapped DTMIterator. I'm not sure whether anyone will need this or not, but let's write it and think about it.


public org.w3c.dom.Node item(int index)
Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null.

Specified by:
item in interface org.w3c.dom.NodeList
item in class DTMNodeListBase
index - Index into the collection.
The node at the indexth position in the NodeList, or null if that is not a valid index.


public int getLength()
The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.

Specified by:
getLength in interface org.w3c.dom.NodeList
getLength in class DTMNodeListBase
