This class is the cornerstone of the ORB Dynamic Invocation Interface (DII), which allows dynamic creation and invocation of requests. A server cannot tell the difference between a client invocation using a client stub and a request using the DII. <P> A <code>Request</code> object consists of: <UL> <LI>the name of the operation to be invoked <LI>an <code>NVList</code> containing arguments for the operation.<BR> Each item in the list is a <code>NamedValue</code> object, which has three parts: <OL> <LI>the name of the argument <LI>the value of the argument (as an <code>Any</code> object) <LI>the argument mode flag indicating whether the argument is for input, output, or both </OL> </UL> <P> <code>Request</code> objects may also contain additional information, depending on how an operation was defined in the original IDL interface definition. For example, where appropriate, they may contain a <code>NamedValue</code> object to hold the return value or exception, a context, a list of possible exceptions, and a list of context strings that need to be resolved. <P> New <code>Request</code> objects are created using one of the <code>create_request</code> methods in the <code>Object</code> class. In other words, a <code>create_request</code> method is performed on the object which is to be invoked.<P><DL><DT><B>See Also: </B><DD><A
