29 * An object that captures the explicit state of a request
30 * for the Dynamic Skeleton Interface (DSI). This class, the
31 * cornerstone of the DSI, is analogous to the <code>Request</code>
32 * object in the DII.
33 * <P>
34 * The ORB is responsible for creating this embodiment of a request,
35 * and delivering it to a Dynamic Implementation Routine (DIR).
36 * A dynamic servant (a DIR) is created by implementing the
37 * <code>DynamicImplementation</code> class,
38 * which has a single <code>invoke</code> method. This method accepts a
39 * <code>ServerRequest</code> object.
40 *
41 * The abstract class <code>ServerRequest</code> defines
42 * methods for accessing the
43 * method name, the arguments and the context of the request, as
44 * well as methods for setting the result of the request either as a
45 * return value or an exception. <p>
46 *
47 * A subtlety with accessing the arguments of the request is that the
48 * DIR needs to provide type information about the
49 * expected arguments, since there is no compiled information about
50 * these. This information is provided through an <code>NVList</code>,
51 * which is a list of <code>NamedValue</code> objects.
52 * Each <code>NamedValue</code> object
53 * contains an <code>Any</code> object, which in turn
54 * has a <code>TypeCode</code> object representing the type
55 * of the argument. <p>
56 *
57 * Similarly, type information needs to be provided for the response,
58 * for either the expected result or for an exception, so the methods
59 * <code>result</code> and <code>except</code> take an <code>Any</code>
60 * object as a parameter. <p>
