| org.xml.sax.ErrorHandler
| ErrorHandler | | public interface ErrorHandler (Code) | | Basic interface for SAX error handlers.
This module, both source code and documentation, is in the
Public Domain, and comes with NO WARRANTY.
See http://www.saxproject.org
for further information.
If a SAX application needs to implement customized error
handling, it must implement this interface and then register an
instance with the XML reader using the
org.xml.sax.XMLReader.setErrorHandler setErrorHandler method. The parser will then report all errors and warnings
through this interface.
WARNING: If an application does not
register an ErrorHandler, XML parsing errors will go unreported
and bizarre behaviour may result.
For XML processing errors, a SAX driver must use this interface
instead of throwing an exception: it is up to the application
to decide whether to throw an exception for different types of
errors and warnings. Note, however, that there is no requirement that
the parser continue to provide useful information after a call to
ErrorHandler.fatalError fatalError (in other words, a SAX driver class
could catch an exception and report a fatalError).

| Method Summary | |
| abstract 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. | | abstract 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. | | abstract 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. |
| error | | abstract public void error(SAXParseException exception) 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.
Filters may use this method to report other, non-XML errors
as well.
Parameters:
exception - The error information encapsulated in aSAX parse exception.
exception:
org.xml.sax.SAXException - Any SAX exception, possiblywrapping another exception.

| fatalError | | abstract public void fatalError(SAXParseException exception) 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:
exception - The error information encapsulated in aSAX parse exception.
exception:
org.xml.sax.SAXException - Any SAX exception, possiblywrapping another exception.
