This interface has been replaced by the SAX2
interface, which includes Namespace support.

Basic interface for SAX (Simple API for XML) parsers.

This was the main event supplier interface for SAX1; it has
been replaced in SAX2 by XMLReader,
which includes Namespace support and sophisticated configurability
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.
Allow an application to request a locale for errors and warnings.
SAX parsers are not required to provide localisation for errors
and warnings; if they cannot support the requested locale,
however, they must throw a SAX exception. Applications may
not request a locale change in the middle of a parse.
locale - A Java Locale object.
SAXException - Throws an exception
(using the previous or default locale) if the
requested locale is not supported.
Allow an application to register a custom entity resolver.
If the application does not register an entity resolver, the
SAX parser will resolve system identifiers and open connections
to entities itself (this is the default behaviour implemented in
Applications may register a new or different entity resolver
in the middle of a parse, and the SAX parser must begin using
the new resolver immediately.
Allow an application to register an error event handler.
If the application does not register an error event handler,
all error events reported by the SAX parser will be silently
ignored, except for fatalError, which will throw a SAXException
(this is the default behaviour implemented by HandlerBase).
Applications may register a new or different handler in the
middle of a parse, and the SAX parser must begin using the new
The application can use this method to instruct the SAX parser
to begin parsing an XML document from any valid input
source (a character stream, a byte stream, or a URI).
Applications may not invoke this method while a parse is in
progress (they should create a new Parser instead for each
additional XML document). Once a parse is complete, an
application may reuse the same Parser object, possibly with a
different input source.
source - The input source for the top-level of the
SAXException - Any SAX exception, possibly
wrapping another exception.
IOException - An IO exception from the parser,
possibly from a byte stream or character stream
supplied by the application.
