javax.xml.transform
public interface ErrorListener
To provide customized error handling, implement this interface and
use the setErrorListener
method to register an instance of the
implmentation with the {@link javax.xml.transform.Transformer}. The
Transformer
then reports all errors and warnings through this
interface.
If an application does not register its own custom
ErrorListener
, the default ErrorListener
is used which reports all warnings and errors to System.err
and does not throw any Exception
s.
Applications are strongly encouraged to register and use
ErrorListener
s that insure proper behavior for warnings and
errors.
For transformation errors, a Transformer
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 the
Transformer
is not required to continue with the transformation
after a call to {@link #fatalError(TransformerException exception)}.
Transformer
s may use this mechanism to report XML parsing
errors as well as transformation errors.
Method Summary | |

abstract void | error(TransformerException exception)
Receive notification of a recoverable error.

abstract void | fatalError(TransformerException exception) Receive notification of a non-recoverable error. The |
abstract void | warning(TransformerException exception)
Receive notification of a warning.

The transformer must continue to try and provide normal transformation after invoking this method. It should still be possible for the application to process the document through to the end if no other errors are encountered.
Parameters: exception The error information encapsulated in a transformer exception.
Throws: javax.xml.transform.TransformerException if the application chooses to discontinue the transformation.
See Also: TransformerException
Receive notification of a non-recoverable error.
The Transformer
must continue to try and provide normal
transformation after invoking this method. It should still be possible for the
application to process the document through to the end if no other errors
are encountered, but there is no guarantee that the output will be
useable.
Parameters: exception The error information encapsulated in a
TransformerException
.
Throws: javax.xml.transform.TransformerException if the application chooses to discontinue the transformation.

{@link javax.xml.transform.Transformer} can use this method to report conditions that are not errors or fatal errors. The default behaviour is to take no action.
After invoking this method, the Transformer must continue with the transformation. It should still be possible for the application to process the document through to the end.
Parameters: exception The warning information encapsulated in a transformer exception.
Throws: javax.xml.transform.TransformerException if the application chooses to discontinue the transformation.
