SAX2 extension handler for lexical events.
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 is an optional extension handler for SAX2 to provide lexical information about an XML document, such as comments and CDATA section boundaries. XML readers are not required to recognize this handler, and it is not part of core-only SAX2 distributions.
The events in the lexical handler apply to the entire document, not just to the document element, and all lexical handler events must appear between the content handler's startDocument and endDocument events.
To set the LexicalHandler for an XML reader, use the
setProperty method
with the property name
http://xml.org/sax/properties/lexical-handler
and an object implementing this interface (or null) as the value.
If the reader does not report lexical events, it will throw a
SAXNotRecognizedException
when you attempt to register the handler.
