org.omg.CORBA
Class NamedValue

java.lang.Object
  extended by org.omg.CORBA.NamedValue

public abstract class NamedValue
extends Object

An object used in the DII and DSI to describe arguments and return values. NamedValue objects are also used in the Context object routines to pass lists of property names and values.

A NamedValue object contains:

The class NamedValue has three methods, which access its fields. The following code fragment demonstrates creating a NamedValue object and then accessing its fields:

    ORB orb = ORB.init(args, null);
    String s = "argument_1";
    org.omg.CORBA.Any myAny = orb.create_any();
    myAny.insert_long(12345);
    int in = org.omg.CORBA.ARG_IN.value;

    org.omg.CORBA.NamedValue nv = orb.create_named_value(
        s, myAny, in);
    System.out.println("This nv name is " + nv.name());
    try {
        System.out.println("This nv value is " + nv.value().extract_long());
        System.out.println("This nv flag is " + nv.flags());
    } catch (org.omg.CORBA.BAD_OPERATION b) {
      System.out.println("extract failed");
    }
 

If this code fragment were put into a main method, the output would be something like the following:

    This nv name is argument_1
    This nv value is 12345
    This nv flag is 1
 

Note that the method value returns an Any object. In order to access the long contained in the Any object, we used the method extract_long.
