All Implemented Interfaces:

wt.util.xml.xpath.XPathCallback

public class NodeListCallback
extends wt.util.xml.xpath.AbstractXPathCallback

This class may be used as a simple callback to obtain a NodeList from a particular xpath. Any attempt to process any other type will result in a DOMException.NOT_SUPPORTED_ERR being thrown back to the calling body.

Supported API: true

Extendable: true

Method Summary

Node	firstNode() Will return the first Node which was satisfied by the xpath through this callback.

void	process(boolean value) process method for the boolean type.
void	process(double value) process method for the double type.
void	process(NodeList value) process method for the NodeList type.
void	process(String value) process method for the String type.
