1008N/A *
1008N/A * <p>This was the main event supplier interface for SAX1; it has
1008N/A * been replaced in SAX2 by {@link org.xml.sax.XMLReader XMLReader},
1008N/A * which includes Namespace support and sophisticated configurability
1008N/A * and extensibility.</p>
1008N/A *
1008N/A * <p>All SAX1 parsers must implement this basic interface: it allows
1008N/A * applications to register handlers for different types of events
1008N/A * and to initiate a parse from a URI, or a character stream.</p>
1008N/A *
1008N/A * <p>All SAX1 parsers must also implement a zero-argument constructor
1008N/A * (though other constructors are also allowed).</p>
1008N/A *
1008N/A * <p>SAX1 parsers are reusable but not re-entrant: the application
1008N/A * may reuse a parser object (possibly with a different input source)
1008N/A * once the first parse has completed successfully, but it may not
1008N/A * invoke the parse() methods recursively within a parse.</p>
1008N/A *
1008N/A * @deprecated This interface has been replaced by the SAX2
1008N/A * {@link org.xml.sax.XMLReader XMLReader}
1008N/A * interface, which includes Namespace support.
