Detailed Description

DDLSAX2Handler inherits from Xerces C++ DefaultHandler.

Author:: Michael Case

DDLSAX2Handler.h - description ------------------- begin: Mon Oct 22 2001 email: case@ucdhep.ucdavis.edu

The DefaultHandler of Xerces C++ provides an interface to the SAX2 event driven processing of XML documents. It does so by providing methods which are redefined by the inheriting class (DDLSAX2Handler in this case) to provide the desired processing for each event.

In this case, we accumulate some statistics. This class does nothing with startElement and endElement events.
