XMLReaderAdapter

extends Object
implements ContentHandler Parser
java.lang.Object
   ↳ org.xml.sax.helpers.XMLReaderAdapter

Class Overview

Adapt a SAX2 XMLReader as a SAX1 Parser.

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 wraps a SAX2 XMLReader and makes it act as a SAX1 Parser. The XMLReader must support a true value for the http://xml.org/sax/features/namespace-prefixes property or parsing will fail with a SAXException; if the XMLReader supports a false value for the http://xml.org/sax/features/namespaces property, that will also be used to improve efficiency.
