public abstract class NamedValue extends Object
NamedValue objects
are also used in the Context
object routines to pass lists of property names and values.
A NamedValue object contains:
NamedValue object is used to
describe arguments to a request, the name will be an argument
identifier specified in the OMG IDL interface definition
for the operation being described.
Any object
ARG_IN.value
ARG_OUT.value
ARG_INOUT.value
NamedValue object represents a property
in a Context object rather than a parameter or
return value
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.
