Class SAXWrapperHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      net.sf.joost.stx.SAXWrapperHandler

All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler, LexicalHandler, TransformerHandler

public class SAXWrapperHandler

extends DefaultHandler

implements TransformerHandler

Wraps a SAX parser (XMLReader) in a TransformerHandler object.

Collects all character data reported by characters and parses them afterwards with a SAX parser (which produces the result of this transformation). Other input events will be ignored.
