Class XSLTErrorListener

java.lang.Object
  net.sf.saxon.StandardErrorListener
      com.saxonica.extra.XSLTErrorListener

All Implemented Interfaces:

Serializable, ErrorListener

public class XSLTErrorListener
extends StandardErrorListener

An ErrorListener for use when running schema-aware XSLT stylesheets. It differs from the standard error listener in that it can produce a stack trace when a run-time error occurs.

XSLTErrorListener

public XSLTErrorListener()

Method Detail

makeAnother

public StandardErrorListener makeAnother(int hostLanguage)

Make a clean ErrorListener. This is necessary because the standard error listener is stateful (it remembers how many errors there have been)

Overrides:

makeAnother in class StandardErrorListener

Parameters:

hostLanguage - the host language (not used by this implementation)

Returns:

a copy of this error listener

setProduceStackTrace

public void setProduceStackTrace(boolean doIt)

Set an option to control whether or not this error listener will produce a stack trace when a run-time error occurs. By default, it will produce a stack trace.

Parameters:

doIt - true if a stack trace is to be produced when an error occurs; false if the stack trace is to be suppressed.

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.

Specified by:

warning in interface ErrorListener

Overrides:

warning in class StandardErrorListener

Parameters:

exception - The warning information encapsulated in a transformer exception.

Throws:

TransformerException - if the application chooses to discontinue the transformation.

See Also:

TransformerException

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

Specified by:

error in interface ErrorListener

Overrides:

error in class StandardErrorListener

Parameters:

exception - The error information encapsulated in a transformer exception.

Throws:

TransformerException - if the application chooses to discontinue the transformation.

See Also:

TransformerException

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.

Specified by:

fatalError in interface ErrorListener

Overrides:

fatalError in class StandardErrorListener

Parameters:

exception - The error information encapsulated in a transformer exception.

Throws:

TransformerException - if the application chooses to discontinue the transformation.

printStackTrace

public static void printStackTrace(PrintStream out,
                                   XPathContext context)

Print a stack trace to a specified output destination
