Class MyXMLHandler

  • All Implemented Interfaces:
    org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

    class MyXMLHandler
    extends org.xml.sax.helpers.DefaultHandler
    Handle events generated while parsing the XML file. This MyXMLHandler is a special one. We just need to save the Pts from the VOI xml file into one chunk vector. We don't need to save the point coordinates into the VOI structure.
