 /**
  * An object containing the information necessary for
  * invoking a method.  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.
