public interface ErrorListenerTo provide customized error handling, implement this interface and use the
setErrorListenermethod to register an instance of the implementation with theTransformer. TheTransformerthen reports all errors and warnings through this interface.If an application does not register its own custom
ErrorListener, the defaultErrorListeneris used which reports all warnings and errors toSystem.errand does not throw anyExceptions. Applications are strongly encouraged to register and useErrorListeners that insure proper behavior for warnings and errors.For transformation errors, a
Transformermust use this interface instead of throwing anException: it is up to the application to decide whether to throw anExceptionfor different types of errors and warnings. Note however that theTransformeris not required to continue with the transformation after a call tofatalError(TransformerException exception).Transformers may use this mechanism to report XML parsing errors as well as transformation errors.- Since:

Method Detail

warning
void warning(TransformerException exception) throws TransformerException
Receive notification of a warning.Transformercan 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:
TransformerException- if the application chooses to discontinue the transformation.- See Also:
TransformerException
-
error
void error(TransformerException exception) throws TransformerException
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- The error information encapsulated in a transformer exception.- Throws:
TransformerException- if the application chooses to discontinue the transformation.- See Also:
TransformerException
-
fatalError
void fatalError(TransformerException exception) throws TransformerException
Receive notification of a non-recoverable error.
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.
- Parameters:
exception- The error information encapsulated in aTransformerException.- Throws:
TransformerException- if the application chooses to discontinue the transformation.- See Also:
TransformerException
