Name

XMLReaderAdapter

Synopsis

This adapter class wraps a SAX2 XMLReader object and makes it behave like a SAX1 Parser object. It is useful when working with a legacy API that requires a deprecated Parser object. Create an XMLReaderAdapter by passing an XMLReader to the XMLReaderAdapter( ) constructor. Then use the resulting object exactly as you would use any other SAX1 Parser object. This class implements ContentHandler so that it can receive SAX events from the XMLReader. But it also implements the Parser interface so that it can have a SAX1 DocumentHandler registered on it. The methods of ContentHandler are implemented to invoke the corresponding methods of the registered DocumentHandler.
