VDLErrorHandler
public class VDLErrorHandler implements ErrorHandler(Code)
This class is the error handler for the parser. It defines how to handle three different kinds of parsing exceptions: warning, error, and fatal error. Here we simply print the error message and the location where the error happend.

Method Summary
public  voiderror(SAXParseException e)
     Receive notification of a recoverable error.

This corresponds to the definition of "error" in section 1.2 of the W3C XML 1.0 Recommendation.

public  voidfatalError(SAXParseException e)
     Receive notification of a non-recoverable error.

This corresponds to the definition of "fatal error" in section 1.2 of the W3C XML 1.0 Recommendation.

public  voidwarning(SAXParseException e)
     Receive notification of a warning.

SAX parsers will use this method to report conditions that are not errors or fatal errors as defined by the XML 1.0 recommendation.




Method Detail
error
public void error(SAXParseException e) throws SAXException(Code)
Receive notification of a recoverable error.

This corresponds to the definition of "error" in section 1.2 of the W3C XML 1.0 Recommendation. For example, a validating parser would use this callback to report the violation of a validity constraint. The default behaviour is to take no action.

The SAX parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end. If the application cannot do so, then the parser should report a fatal error even if the XML 1.0 recommendation does not require it to do so.
Parameters:
  e - is an error generated by the SAX parser.
See Also:   org.xml.sax.ErrorHandler.error(org.xml.sax.SAXParseException)




fatalError
public void fatalError(SAXParseException e) throws SAXException(Code)
Receive notification of a non-recoverable error.

This corresponds to the definition of "fatal error" in section 1.2 of the W3C XML 1.0 Recommendation. For example, a parser would use this callback to report the violation of a well-formedness constraint.

The application must assume that the document is unusable after the parser has invoked this method, and should continue (if at all) only for the sake of collecting addition error messages: in fact, SAX parsers are free to stop reporting any other events once this method has been invoked.
Parameters:
  e - is a fatal error generated by the SAX parser.
See Also:   org.xml.sax.ErrorHandler.fatalError(org.xml.sax.SAXParseException)




warning
public void warning(SAXParseException e) throws SAXException(Code)
Receive notification of a warning.

SAX parsers will use this method to report conditions that are not errors or fatal errors as defined by the XML 1.0 recommendation. The default behaviour is to take no action.

The SAX parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end.
Parameters:
  e - is a warning generated by the SAX parser.
See Also:   org.xml.sax.ErrorHandler.warning(org.xml.sax.SAXParseException)
