java.lang.Object org.xml.sax.helpers.XMLReaderAdapter
public class XMLReaderAdapter
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.

cannot be instantiated or if the
org.xml.sax.driver property is not specified.public XMLReaderAdapter(XMLReader xmlReader)
Create a new adapter, wrapped around a SAX2 XMLReader. The adapter will make the XMLReader act like a SAX1 Parser.
