Method Detail

ensureLocationSet

public static void ensureLocationSet(TransformerException exception)

error

public void error(SAXParseException exception)
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: exception The error information encapsulated in a SAX parse exception.

Throws: SAXException Any SAX exception, possibly wrapping another exception.

error

public void error(TransformerException exception)
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: exception The error information encapsulated in a SAX parse exception.

Throws: javax.xml.transform.TransformerException Any SAX exception, possibly wrapping another exception.

See Also: javax.xml.transform.TransformerException

fatalError

public void fatalError(SAXParseException exception)
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: exception The error information encapsulated in a SAX parse exception.

Throws: SAXException Any SAX exception, possibly wrapping another exception.

fatalError

public void fatalError(TransformerException exception)
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: exception The error information encapsulated in a SAX parse exception.

Throws: javax.xml.transform.TransformerException Any SAX exception, possibly wrapping another exception.

getErrorWriter

public PrintWriter getErrorWriter()
Retrieve java.io.PrintWriter to which errors are being directed.

Returns: The PrintWriter installed via the constructor or the default PrintWriter

printLocation

public static void printLocation(PrintStream pw, TransformerException exception)

printLocation

public static void printLocation(PrintStream pw, SAXParseException exception)

printLocation

public static void printLocation(PrintWriter pw, Throwable exception)

warning

public void warning(SAXParseException exception)
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: exception The warning information encapsulated in a SAX parse exception.

Throws: SAXException Any SAX exception, possibly wrapping another exception.

warning

public void warning(TransformerException exception)
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: exception The warning information encapsulated in a SAX parse exception.

Throws: javax.xml.transform.TransformerException Any SAX exception, possibly wrapping another exception.
