Parameters:
- ch - The characters.
- start - The start position in the character array.
- length - The number of characters to use from the character array.
Throws:
- org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

See Also: ContentHandler.endDocument(),

  Receive notification of the end of an element.

  Receive notification of a recoverable parser error.

  Receive notification of a recoverable parser error.

The default implementation does nothing. Application writers may override this method in a subclass to take specific actions for each error, such as inserting the message in a log file or printing it to the console.

See Also: ErrorHandler.warning(org.xml.sax.SAXParseException), SAXParseException,

  Report a fatal XML parsing error.

  Report a fatal XML parsing error.

The default implementation throws a SAXParseException. Application writers may override this method in a subclass if they need to take specific actions for each fatal error (such as collecting all of the errors into a single report): in any case, the application must stop all regular processing when this method is invoked, since the document is no longer reliable, and the parser may no longer report parsing events.

Parameters:
- e - The error information encoded as an exception.
Throws:
- org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
See Also: ErrorHandler.fatalError(org.xml.sax.SAXParseException), SAXParseException,

Parameters:
- ch - The whitespace characters.
- start - The start position in the character array.
- length - The number of characters to use from the character array.
Throws:
- org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
See Also: ContentHandler.ignorableWhitespace(char[], int, int),

  Receive notification of a notation declaration.

  Receive notification of a notation declaration.

Throws:
- org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

  Receive notification of the start of an element.

  Receive notification of the start of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the start of each element (such as allocating a new tree node or writing output to a file).

- localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.
