java.lang.Objectorg.omg.CORBA.ContextList
public abstract class ContextList
An object containing a modifiable list of String objects
that represent property names.
This class is used in Request operations to
describe the contexts that need to be resolved and sent with the
invocation. (A context is resolved by giving a property name
and getting back the value associated with it.) This is done
by calling the Context method
get_values and supplying a string from a
ContextList object as the third parameter.
The method get_values returns an NVList
object containing the NamedValue objects that hold
the value(s) identified by the given string.
A ContextList object is created by the ORB, as
illustrated here:
ORB orb = ORB.init(args, null); org.omg.CORBA.ContextList ctxList = orb.create_context_list();The variable
ctxList represents an empty
ContextList object. Strings are added to
the list with the method add, accessed
with the method item, and removed with the
method remove.

String object to this ContextList
object.
ctx - the String object to be added
public abstract String item(int index)
throws Bounds
String object at the given index.
