Method Detail

setLocale

public void setLocale(Locale)
               throws SAXException

Description copied from interface: Parser

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.

Specified by:

setLocale in interface Parser

Parameters:

- A Java Locale object.

Throws:

SAXException - Throws an exception (using the previous or default locale) if the requested locale is not supported.

See Also:

SAXException, SAXParseException

setEntityResolver

public void setEntityResolver(EntityResolver)

Description copied from interface: Parser

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 HandlerBase).

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.

Specified by:

setEntityResolver in interface Parser

Parameters:

- The object for resolving entities.

See Also:

EntityResolver, HandlerBase

setDTDHandler

public void setDTDHandler(DTDHandler)

Description copied from interface: Parser

Allow an application to register a DTD event handler.

If the application does not register a DTD handler, all DTD events reported by the SAX parser will be silently ignored (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 handler immediately.

Specified by:

setDTDHandler in interface Parser

Parameters:

- The DTD handler.

See Also:

DTDHandler, HandlerBase

setDocumentHandler

public void setDocumentHandler(DocumentHandler)

Description copied from interface: Parser

Allow an application to register a document event handler.

If the application does not register a document handler, all document events reported by the SAX parser will be silently ignored (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 handler immediately.

Specified by:

setDocumentHandler in interface Parser

Parameters:

- The document handler.

See Also:

DocumentHandler, HandlerBase

setErrorHandler

public void setErrorHandler(ErrorHandler)

Description copied from interface: Parser

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 handler immediately.

Specified by:

setErrorHandler in interface Parser

Parameters:

- The error handler.

See Also:

ErrorHandler, SAXException, HandlerBase

parse

public void parse(String)
           throws IOException,
                  SAXException

Description copied from interface: Parser

Parse an XML document from a system identifier (URI).

This method is a shortcut for the common case of reading a document from a system identifier. It is the exact equivalent of the following:

 parse(new InputSource(systemId));
 

If the system identifier is a URL, it must be fully resolved by the application before it is passed to the parser.

Specified by:

parse in interface Parser

Parameters:

- The system identifier (URI).

Throws:

IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

Parser.parse(org.xml.sax.InputSource)

parse

public void parse(InputSource)
           throws IOException,
                  SAXException

Description copied from interface: Parser

Parse an XML document.

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.

Specified by:

parse in interface Parser

Parameters:

- The input source for the top-level of the XML document.

Throws:

IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

SAXException - Any SAX exception, possibly wrapping another exception.
