All Implemented Interfaces:

ComponentInputI, ComponentOutputI, org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.xml.sax.ext.LexicalHandler, org.xml.sax.XMLFilter, org.xml.sax.XMLReader

public class SAXFactoryTree

extends SAXFactory

implements ComponentOutputI, ComponentInputI

The SAXFactoryTree class provides a relatively simple mechanism for creating new MOE components, hardwired to the components provided in the com.simonstl.moe package. It in turn relies on the ComponentFactory class.

This class extends XMLFilterImpl rather than DefaultHandler so that it can be used as a pass-through if appropriate.
