Class JMUnmarshallerHandlerImpl

java.lang.Object

org.apache.ws.jaxme.impl.JMUnmarshallerHandlerImpl

All Implemented Interfaces:

UnmarshallerHandler, JMUnmarshallerHandler, org.xml.sax.ContentHandler

public class JMUnmarshallerHandlerImpl
extends java.lang.Object
implements JMUnmarshallerHandler

Implementation of a JMUnmarshallerHandler; the UnmarshallerHandler receives SAX events which he silently discards, as long as the first startElement event is seen. Depending on namespace URI and local name, the Unmarshallerhandler creates a new instance of JMHandler and from now on forwards all SAX events to the JMHandler.
