| duke@1 | 29 | * A modifiable list containing <code>NamedValue</code> objects. |
| duke@1 | 30 | * <P> |
| duke@1 | 31 | * The class <code>NVList</code> is used as follows: |
| duke@1 | 32 | * <UL> |
| duke@1 | 33 | * <LI>to describe arguments for a <code>Request</code> object |
| duke@1 | 34 | * in the Dynamic Invocation Interface and |
| duke@1 | 35 | * the Dynamic Skeleton Interface |
| duke@1 | 36 | * <LI>to describe context values in a <code>Context</code> object |
| duke@1 | 37 | * </UL> |
| duke@1 | 38 | * <P> |
| duke@1 | 39 | * Each <code>NamedValue</code> object consists of the following: |
| duke@1 | 40 | * <UL> |
| duke@1 | 41 | * <LI>a name, which is a <code>String</code> object |
| duke@1 | 42 | * <LI>a value, as an <code>Any</code> object |
| duke@1 | 43 | * <LI>an argument mode flag |
| duke@1 | 44 | * </UL> |
| duke@1 | 45 | * <P> |
| duke@1 | 46 | * An <code>NVList</code> object |
| duke@1 | 47 | * may be created using one of the following |
| duke@1 | 48 | * <code>ORB</code> methods: |
| duke@1 | 49 | * <OL> |
| duke@1 | 50 | * <LI><code>org.omg.CORBA.ORB.create_list</code> |
| duke@1 | 51 | * <PRE> |
| duke@1 | 52 | * org.omg.CORBA.NVList nv = orb.create_list(3); |
| duke@1 | 53 | * </PRE> |
| duke@1 | 54 | * The variable <code>nv</code> represents a newly-created |
| duke@1 | 55 | * <code>NVList</code> object. The argument is a memory-management |
| duke@1 | 56 | * hint to the orb and does not imply the actual length of the list. |
| duke@1 | 57 | * If, for example, you want to use an <code>NVList</code> object |
| duke@1 | 58 | * in a request, and the method being invoked takes three parameters, |
| duke@1 | 59 | * you might optimize by supplying 3 to the method |
| duke@1 | 60 | * <code>create_list</code>. Note that the new <code>NVList</code> |
| duke@1 | 61 | * will not necessarily have a length of 3; it |
| duke@1 | 62 | * could have a length of 2 or 4, for instance. |
| duke@1 | 63 | * Note also that you can add any number of |
| duke@1 | 64 | * <code>NamedValue</code> objects to this list regardless of |
| duke@1 | 65 | * its original length. |
| duke@1 | 66 | * <P> |
| duke@1 | 67 | * <LI><code>org.omg.CORBA.ORB.create_operation_list</code> |
| duke@1 | 68 | * <PRE> |
| duke@1 | 69 | * org.omg.CORBA.NVList nv = orb.create_operation_list(myOperationDef); |
| duke@1 | 70 | * </PRE> |
| duke@1 | 71 | * The variable <code>nv</code> represents a newly-created |
| duke@1 | 72 | * <code>NVList</code> object that contains descriptions of the |
| duke@1 | 73 | * arguments to the method described in the given |
| duke@1 | 74 | * <code>OperationDef</code> object. |
| duke@1 | 75 | * </OL> |
| duke@1 | 76 | * <P> |
| duke@1 | 77 | * The methods in the class <code>NVList</code> all deal with |
| duke@1 | 78 | * the <code>NamedValue</code> objects in the list. |
| duke@1 | 79 | * There are three methods for adding a <code>NamedValue</code> object, |
| duke@1 | 80 | * a method for getting the count of <code>NamedValue</code> objects in |
| duke@1 | 81 | * the list, a method for retrieving a <code>NamedValue</code> object |
| duke@1 | 82 | * at a given index, and a method for removing a <code>NamedValue</code> object |
| duke@1 | 83 | * at a given index. |
