public interface NamingContextExtOperations
extends NamingContextOperations

NamingContextExt is the extension of NamingContext which contains a set of name bindings in which each name is unique and is part of Interoperable Naming Service. Different names can be bound to an object in the same or different contexts at the same time. Using NamingContextExt, you can use URL-based names to bind and resolve.

See CORBA COS Naming Specification.

Method Summary

Object resolve_str(String sn)
          This operation resolves the Stringified name into the object reference.

NameComponent[] to_name(String sn)
          This operation converts a Stringified Name into an equivalent array of Name Components.

String to_string(NameComponent[] n)
          This operation creates a stringified name from the array of Name components.

String to_url(String addr, String sn)
          This operation creates a URL based "iiopname://" format name from the Stringified Name of the object.
