Example of Generics and Service API.

[Peter Firmstone <ji...@zeus.net.au>]

Check out an example of utilising Generics and maintaining runtime type 
safety with Service API.

See:

http://svn.apache.org/viewvc/incubator/river/jtsk/skunk/pepe/src/org/apache/river/api/lookup/

StreamServiceRegistrar and MarshalledServiceItem (extends ServiceItem) 
are part of the Service API.

ResultStream<T>, is an interface using generics.

StreamServiceRegistrar uses ResultStream, but reverts to the default 
type, Object.

ServiceResultStreamFilter and ServiceResultStreamUnmarshaller are client 
utility classes that utilise Generic's, implement ResultStream and are 
used by the client to manipulate the results from StreamServiceRegistrar 
and MarshalledServiceItem.


Cheers,

Peter.
