Method Details

error

public void error(SAXParseException ex)
            throws SAXException
Throw a SAXException if the parser issues an error. SAX parsers issue an error to report conditions that are errors by the W3C XML recommendation but are recoverable errors. The default behavior for errors is to take no action; we throw an exception since we want our XML documents to be well-formed and valid.

fatalError

public void fatalError(SAXParseException ex)
            throws SAXException
Throw a SAXException if the parser issues a fatal error. SAX parsers issue a fatal error if it cannot continue parsing the XML document. The default behavior for fatal errors is to throw an exception of type SAXException.

warning

public void warning(SAXParseException ex)
            throws SAXException
Throw a SAXException if the parser issues a warning. SAX parsers issue a warning to report conditions that are not errors or fatal errors by the XML 1.0 recommendation. By definition, the parser could recover from a warning. The default parser action for a warning is to take no action; by throwing an exception, we ensure that all XML documents are up to our high standards of quality.
