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 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 Exceptions.
Applications are strongly encouraged to register and use
ErrorListeners 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 fatalError(TransformerException exception).
Transformers may use this mechanism to report XML parsing
errors as well as transformation errors.
| Modifier and Type | Method and Description |
|---|---|
void |
error(TransformerException exception)
Receive notification of a recoverable error.
|
void |
fatalError(TransformerException exception)
Receive notification of a non-recoverable error.
|
void |
warning(TransformerException exception)
Receive notification of a warning.

void warning(TransformerException exception) throws TransformerException
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.

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.

The processor may choose to continue, but will not normally proceed to a successful completion.
The method should throw an exception if it is unable to process the error, or if it wishes execution to terminate immediately. The processor will not necessarily honor this request.
