public abstract class LastChangeParser
extends SAXParser

Reads and writes the "LastChange" XML content.

Validates against a schema if the SAXParser.getSchemaSources() method doesn't return null.

Note: This is broken on most devices and with most services out in the wild. In fact, you might want to use polling the service with actions, to get its status, instead of GENA. Polling can be expensive on low-power control points, however.
