/**
 * The @QueryRequest annotation marks a SimpleBamService method as handling
 * a result from an RPC query.  Queries are matched to results using a
 * long id, which is unique for each query in the connection.
 *
 * <code><pre>
 * @QueryResult
 * void queryResult(long id, String to, String from, MyResult value)
 * </pre></code>
 *
 * A ping RPC query result would look like:
 *
 * <code><pre>
 * @QueryResult
 * public void pingResult(long id, String to, String from, PingQuery value)
 * {
 *   System.out.println("Ping: " + value
 *                    + " {id:" + id + ", to:" + to + ", from:" + from + "}");
 * }
