SAXC14nCanonicalizerImpl

public SAXC14nCanonicalizerImpl()
Creates a new instance of SAXC14nCanonicalzerImpl

Method Detail

getNSContext

public org.xml.sax.helpers.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.
