public abstract class ContextList extends Object
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
