Interface IErrorHandler
Basic interface for SAX error handlers.
Namespace: Sax
Assembly: Lucene.Net.Benchmark.dll
Syntax
public interface IErrorHandler
Remarks
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. Seehttp://www.saxproject.org for further information.
If a SAX application needs to implement customized error
handling, it must implement this interface and then register an
instance with the XML reader using the
Error
WARNING: If an application does not
register an ErrorHandler, XML parsing errors will go unreported,
except that SAXParseExceptions will be thrown for fatal errors.
In order to detect validity errors, an ErrorHandler that does something
with Error(SAXParse
For XML processing errors, a SAX driver must use this interface
in preference to 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 there is no requirement that
the parser continue to report additional errors after a call to
Fatal
Methods
| Improve this Doc View SourceError(SAXParseException)
Receive notification of a recoverable error.
Declaration
void Error(SAXParseException exception)
Parameters
Type | Name | Description |
---|---|---|
SAXParse |
exception | The error information encapsulated in a SAX parse exception. |
Remarks
This corresponds to the definition of "error" in section 1.2 of the W3C XML 1.0 Recommendation.For example, a validating parser would use this callback to report the violation of a validity constraint.The default behaviour is to take no action.
The SAX parser 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. If the application cannot do so, then the parser should report a fatal error even if the XML recommendation does not require it to do so.
Filters may use this method to report other, non-XML errors as well.
Exceptions
Type | Condition |
---|---|
SAXException | Any SAX exception, possibly wrapping another exception. |

| Improve this Doc View SourceFatalError(SAXParseException)
Receive notification of a non-recoverable error.
Declaration
void FatalError(SAXParseException exception)
Parameters
Type | Name | Description |
---|---|---|
SAXParse |
exception | The error information encapsulated in a SAX parse exception. |
Remarks
There is an apparent contradiction between the
documentation for this method and the documentation for
End
This corresponds to the definition of "fatal error" in section 1.2 of the W3C XML 1.0 Recommendation.For example, a parser would use this callback to report the violation of a well-formedness constraint.
The application must assume that the document is unusable after the parser has invoked this method, and should continue (if at all) only for the sake of collecting additional error messages: in fact, SAX parsers are free to stop reporting any other events once this method has been invoked.
Exceptions
Type | Condition |
---|---|
SAXException | Any SAX exception, possibly wrapping another exception. |

| Improve this Doc View SourceWarning(SAXParseException)
Receive notification of a warning.
Declaration
void Warning(SAXParseException exception)
Parameters
Type | Name | Description |
---|---|---|
SAXParse |
exception | The warning information encapsulated in a SAX parse exception. |
Remarks
SAX parsers will use this method to report conditions that are not errors or fatal errors as defined by the XML recommendation.The default behaviour is to take no action.
The SAX parser 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.
Filters may use this method to report other, non-XML warnings as well.
