void marshal(Exchange exchange,
             Object graph,
             OutputStream stream)

```
    Marshals the object to the given Stream.
    
    Parameters:
    
    exchange - the current exchange
    
    graph - the object to be marshalled
    
    stream - the output stream to write the marshalled result to

Object unmarshal(Exchange exchange,
                 InputStream stream)
          throws Exception
```
    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.
    
    Parameters:
    
    exchange - the current exchange
    
    stream - the input stream with the object to be unmarshalled
    
    Returns:
