All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public class TermListHandler

extends org.xml.sax.helpers.DefaultHandler

Parses and returns a list of all terms in an XML termlist, creating TermInfo objects. These objects are used extensively by the TermTool, in lieu of direct manipulation of the DOM. There is, no doubt, considerable inefficiency here, and we could probably use much less memory and improve speed. But let's not be too hasty to break what works.
