Class SAXDriver

com.microstar.xml.SAXDriver

All Implemented Interfaces:

XmlHandler

public class SAXDriver

implements XmlHandler

A SAX driver for Microstar's Ælfred XML parser.

This driver acts as a front-end for Ælfred, and translates Ælfred's events into SAX events. It implements the SAX parser interface, and you can use it without directly calling Ælfred at all:

 org.xml.sax.Parser parser = new com.microstar.xml.SAXDriver();
 

When you are using SAX, you do not need to use the XmlParser or XmlHandler classes at all: this class is your entry point.

This driver is based on the 1.0gamma version of SAX, available from http://www.megginson.com/SAX/

Version:

1.1
