package jdk.internal.org.xml.sax;
Encapsulate a general SAX error or warning.
This module, both source code and documentation, is in the
Public Domain, and comes with NO WARRANTY.
See http://www.saxproject.org
for further information.
This class can contain basic error or warning information from
either the XML parser or the application: a parser writer or
application writer can subclass it to provide additional
functionality. SAX handlers may throw this exception or
any exception subclassed from it.
If the application needs to pass through other types of
exceptions, it must wrap those exceptions in a SAXException
or an exception derived from a SAXException.
If the parser or application needs to include information about a specific location in an XML document, it should use the SAXParseException subclass.
Author: David Megginson See Also: - SAXParseException
