public void marshal(Exchange exchange,
                    Object graph,
                    OutputStream stream)
             throws Exception

Description copied from interface: DataFormat

Marshals the object to the given Stream.

Specified by:

marshal in interface DataFormat

Parameters:

exchange - the current exchange

graph - the object to be marshalled

stream - the output stream to write the marshalled result to

Throws:

unmarshal

public Object unmarshal(Exchange exchange,
                        InputStream inputStream)
                 throws Exception

Description copied from interface: DataFormat

Unmarshals the given stream into an object.

Notice: The result is set as body on the exchange OUT message. It is possible to mutate the OUT message provided in the given exchange parameter. For instance adding headers to the OUT message will be preserved.

It's also legal to return the same passed exchange as is but also a Message object as well which will be used as the OUT message of exchange.

Specified by:

unmarshal in interface DataFormat

Parameters:

exchange - the current exchange

inputStream - the input stream with the object to be unmarshalled

Returns:

the unmarshalled object

Throws:

Exception - can be thrown

doStart

protected void doStart()
                throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: See ServiceSupport.doStop() for more details.

Specified by:

doStart in class ServiceSupport

Throws:

Exception

See Also:

ServiceSupport.doStop()

doStop

protected void doStop()
               throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: Camel will invoke this ServiceSupport.doStop() method when the service is being stopped. This method will also be invoked if the service is still in uninitialized state (eg has not been started). The method is always called to allow the service to do custom logic when the service is being stopped, such as when CamelContext is shutting down.

Specified by:

doStop in class ServiceSupport

Throws:

Exception

ServiceSupport.doStart()
