ErrorListener
public
interface
ErrorListener
| javax.xml.transform.ErrorListener
|
To provide customized error handling, implement this interface and
use the setErrorListener method to register an instance of the
implementation 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(javax.xml.transform.TransformerException).
Transformers may use this mechanism to report XML parsing
errors as well as transformation errors.
Summary
Public methods
public abstract void error (TransformerException exception)
Receive notification of a 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.
| Parameters |
|---|
exception |
TransformerException: The error information encapsulated in a
transformer exception. |
public abstract void fatalError (TransformerException exception)
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 |
TransformerException: The error information encapsulated in a
TransformerException. |
public abstract void warning (TransformerException exception)
Receive notification of a warning.
Transformer can use this method to report
conditions that are not errors or fatal errors. The default behavior
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 |
TransformerException: The warning information encapsulated in a
transformer exception. |
