- org.xml.sax.helpers.XMLReaderAdapter

All Implemented Interfaces:

ContentHandler, Parser
```
public class XMLReaderAdapter
extends Object
implements Parser, ContentHandler
```
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.

Since:

SAX 2.0
