This class, the cornerstone of the DSI, is analogous to the <code>Request</code> object in the DII. <P> The ORB is responsible for creating this embodiment of a request, and delivering it to a Dynamic Implementation Routine (DIR). A dynamic servant (a DIR) is created by implementing the <code>DynamicImplementation</code> class, which has a single <code>invoke</code> method. This method accepts a <code>ServerRequest</code> object. The abstract class <code>ServerRequest</code> defines methods for accessing the method name, the arguments and the context of the request, as well as methods for setting the result of the request either as a return value or an exception. <p> A subtlety with accessing the arguments of the request is that the DIR needs to provide type information about the expected arguments, since there is no compiled information about these. This information is provided through an <code>NVList</code>, which is a list of <code>NamedValue</code> objects. Each <code>NamedValue</code> object contains an <code>Any</code> object, which in turn has a <code>TypeCode</code> object representing the type of the argument. <p> Similarly, type information needs to be provided for the response, for either the expected result or for an exception, so the methods <code>result</code> and <code>except</code> take an <code>Any</code> object as a parameter. <p><P><DL><DT><B>See Also: </B><DD><A HREF="../../../org/omg/CORBA/DynamicImplementation.html"><CODE>DynamicImplementation</CODE></A>, <A HREF="../../../org/omg/CORBA/NVList.html"><CODE>NVList</CODE></A>, <A HREF="../../../org/omg/CORBA/NamedValue.html"><CODE>NamedValue</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../org/omg/CORBA/ServerRequest.html#ServerRequest()">ServerRequest</A></B>()</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ServerRequest.html#arguments(org.omg.CORBA.NVList)">arguments</A></B>(<A HREF="../../../org/omg/CORBA/NVList.html">NVList</A> args)</CODE><BR> Specifies method parameter types and retrieves "in" and "inout" argument values.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>abstract <A HREF="../../../org/omg/CORBA/Context.html">Context</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ServerRequest.html#ctx()">ctx</A></B>()</CODE><BR> Returns the context information specified in IDL for the operation when the operation is not an attribute access and the operation's IDL definition contains a context expression;
