Receive notification of a non-recoverable error.
There is an apparent contradiction between the documentation for this method and the documentation for {@link org.xml.sax.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.
@param exception The error information encapsulated in aSAX parse exception.
@exception org.xml.sax.SAXException Any SAX exception, possiblywrapping another exception.
