If a SAX application needs to implement customized error handling,
it must implement this interface and then register an instance with the
SAX parser using the parser's XParser::setErrorhandler
method. The parser will then report all errors and warnings through this
interface.
This interface is a slight adaption of the Java interface
org.xml.sax.ErrorHandler
. In IDL, no exception can be passed
as an argument, so an any
serves as the container. The type of the
exception is SAXParseException or an instance of a derived class.
