 * Base ActorStream implementation using introspection and

 * <h2>Message Handling</h2>
 *
 * To handle a message, create a method with the proper signature for
 * the expected payload type and
 * annotate it with {@link com.caucho.bam.Message @Message}.  To send
 * a response message or query, use <code>getBrokerStream()</code> or
 * <code>getClient()</code>.

 * @Message
 * public void myMessage(String to, String from, MyPayload payload);
