Method Details

error

public void error(TransformerException exception)
            throws TransformerException
Receive notification of a recoverable error.

The transformer 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.

The action of the standard error listener depends on the recovery policy that has been set, which may be one of RECOVER_SILENTLY, RECOVER_WITH_WARNING, or DO_NOT_RECOVER

Parameters:
exception - The error information encapsulated in a transformer exception.

fatalError

public void fatalError(TransformerException exception)
            throws TransformerException
Receive notification of a non-recoverable error.

The application must assume that the transformation cannot continue after the Transformer has invoked this method, and should continue (if at all) only to collect addition error messages. In fact, Transformers are free to stop reporting events once this method has been invoked.

Parameters:
exception - The error information encapsulated in a transformer exception.

getExpandedMessage

public static String getExpandedMessage(TransformerException err)
Get a string containing the message for this exception and all contained exceptions

getLocationMessage

public static String getLocationMessage(TransformerException err)
Get a string identifying the location of an error.

setErrorOutput

public void setErrorOutput(PrintStream writer)
Set output destination for error messages (default is System.err)
Parameters:
writer - The PrintStream to use for error messages

setRecoveryPolicy

public void setRecoveryPolicy(int policy)
Set the recovery policy

warning

public void warning(TransformerException exception)
            throws TransformerException
Receive notification of a warning.

Transformers 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.
