java.lang.Object org.apache.xerces.util.ErrorHandlerProxy
public abstract class ErrorHandlerProxy
Wraps XMLErrorHandler
and make it look like a SAX ErrorHandler
.
The derived class should override the getErrorHandler()
method
so that it will return the correct XMLErrorHandler
instance.
This method will be called whenever an error/warning is found.
Experience shows that it is better to store the actual
XMLErrorHandler
in one place and looks up that variable,
rather than copying it into every component that needs an error handler
and update all of them whenever it is changed, IMO.

public void error(SAXParseException e) throws SAXException
ErrorHandler
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.

wrapping another exception.SAXParseException
public void fatalError(SAXParseException e) throws SAXException
ErrorHandler
There is an apparent contradiction between the
documentation for this method and the documentation for ContentHandler.endDocument()
. Until this ambiguity
is resolved in a future major release, clients should make no
assumptions about whether endDocument() will or will not be
invoked when the parser has reported a fatalError() or thrown
an exception.
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.

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.
