29 * A modifiable list containing <code>NamedValue</code> objects.
30 * <P>
31 * The class <code>NVList</code> is used as follows:
32 * <UL>
33 * <LI>to describe arguments for a <code>Request</code> object
34 * in the Dynamic Invocation Interface and
35 * the Dynamic Skeleton Interface
36 * <LI>to describe context values in a <code>Context</code> object
37 * </UL>
38 * <P>
39 * Each <code>NamedValue</code> object consists of the following:
40 * <UL>
41 * <LI>a name, which is a <code>String</code> object
42 * <LI>a value, as an <code>Any</code> object
43 * <LI>an argument mode flag
44 * </UL>
45 * <P>
46 * An <code>NVList</code> object
47 * may be created using one of the following
48 * <code>ORB</code> methods:
49 * <OL>
50 * <LI><code>org.omg.CORBA.ORB.create_list</code>
51 * <PRE>
52 * org.omg.CORBA.NVList nv = orb.create_list(3);
53 * </PRE>
54 * The variable <code>nv</code> represents a newly-created
55 * <code>NVList</code> object. The argument is a memory-management
56 * hint to the orb and does not imply the actual length of the list.
57 * If, for example, you want to use an <code>NVList</code> object
58 * in a request, and the method being invoked takes three parameters,
59 * you might optimize by supplying 3 to the method
60 * <code>create_list</code>. Note that the new <code>NVList</code>
61 * will not necessarily have a length of 3; it
62 * could have a length of 2 or 4, for instance.
63 * Note also that you can add any number of
64 * <code>NamedValue</code> objects to this list regardless of
65 * its original length.
66 * <P>
67 * <LI><code>org.omg.CORBA.ORB.create_operation_list</code>
68 * <PRE>
69 * org.omg.CORBA.NVList nv = orb.create_operation_list(myOperationDef);
70 * </PRE>
71 * The variable <code>nv</code> represents a newly-created
72 * <code>NVList</code> object that contains descriptions of the
73 * arguments to the method described in the given
74 * <code>OperationDef</code> object.
75 * </OL>
76 * <P>
77 * The methods in the class <code>NVList</code> all deal with
78 * the <code>NamedValue</code> objects in the list.
79 * There are three methods for adding a <code>NamedValue</code> object,
80 * a method for getting the count of <code>NamedValue</code> objects in
81 * the list, a method for retrieving a <code>NamedValue</code> object
82 * at a given index, and a method for removing a <code>NamedValue</code> object
83 * at a given index.
84 *
