Class TransformerHandlerImpl

java.lang.Object
  net.sf.joost.trax.TransformerHandlerImpl

All Implemented Interfaces:

Constants, ContentHandler, DTDHandler, LexicalHandler, TransformerHandler

public class TransformerHandlerImpl

extends Object

implements TransformerHandler, Constants

This class implements the TransformerHandler-Interface for TraX. This class could be used with a SAXResult. So you can simply downcast the TransformerFactory to a SAXTransformerFactory, calling getTransformerHandler() and process the transformation with a Sax-Parser. TransformerHandler acts as a proxy an propagates the Sax-Events to the underlying joost-stx-engine the Processor-class
