Method Detail

getNSContext

public NamespaceSupport getNSContext()

warning

public void warning(SAXParseException e)
             throws SAXException

Receive notification of a parser warning.

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

Parameters:

e - The warning information encoded as an exception.

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

ErrorHandler.warning(org.xml.sax.SAXParseException), SAXParseException

error

public void error(SAXParseException e)
           throws SAXException

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 warning information encoded as an exception.

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

ErrorHandler.warning(org.xml.sax.SAXParseException), SAXParseException

fatalError

public void fatalError(SAXParseException e)
                throws SAXException

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:

SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

ErrorHandler.fatalError(org.xml.sax.SAXParseException), SAXParseException

                         throws SAXException

Receive notification of ignorable whitespace in element content.

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

Specified by:

                                 IOException

Tells the parser to resolve the systemId against the baseURI and read the entity text from that resulting absolute URI.
