By default, do nothing. Application writers may override this method to take specific actions for each chunk of character data (such as adding the data to a node or buffer, or printing it to a file).

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.

  Receive notification of the end of the document.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of a document (such as finalising a tree or closing an output file).

- org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
See Also: ContentHandler.endDocument(),

  Receive notification of the end of an element.

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

Parameters:
- uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.
- localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.

See Also: ContentHandler.endPrefixMapping(java.lang.String),

  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.

Parameters:
- e - The error information encoded as an exception.
Throws:
- org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
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.

By default, do nothing. Application writers may override this method in a subclass if they wish to keep track of the notations declared in a document.

Parameters:
- target - The processing instruction target.
- data - The processing instruction data, or null if none is supplied.
Throws:
- org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
See Also: ContentHandler.processingInstruction(java.lang.String, java.lang.String),

  Resolve an external entity.

  Resolve an external entity.

Always return null, so that the parser will use the system identifier provided in the XML document. This method implements the SAX default behaviour: application writers can override it in a subclass to do special translations such as catalog lookups or URI redirection.

Returns: The new input source, or null to require the default behaviour.
Parameters:
- publicId - The public identifier, or null if none is available.
- systemId - The system identifier provided in the XML document.
Throws:
- java.io.IOException - If there is an error setting up the new input source.

  Receive notification of the start of an element.
