Examples of org.xml.sax.Parser

org.xml.sax.Parser
axproject.org'>http://www.saxproject.org for further information.
This was the main event supplier interface for SAX1; it has been replaced in SAX2 by {@link org.xml.sax.XMLReader XMLReader}, which includes Namespace support and sophisticated configurability and extensibility.

All SAX1 parsers must implement this basic interface: it allows applications to register handlers for different types of events and to initiate a parse from a URI, or a character stream.

All SAX1 parsers must also implement a zero-argument constructor (though other constructors are also allowed).

SAX1 parsers are reusable but not re-entrant: the application may reuse a parser object (possibly with a different input source) once the first parse has completed successfully, but it may not invoke the parse() methods recursively within a parse.
@deprecated This interface has been replaced by the SAX2{@link org.xml.sax.XMLReader XMLReader}interface, which includes Namespace support. @since SAX 1.0 @author David Megginson @version 2.0.1 (sax2r2) @see org.xml.sax.EntityResolver @see org.xml.sax.DTDHandler @see org.xml.sax.DocumentHandler @see org.xml.sax.ErrorHandler @see org.xml.sax.HandlerBase @see org.xml.sax.InputSource
