Detailed Description

Defines a wrapper class that holds the root Naming Context.

This class either finds an existing Naming Service (if the flag is set) or creates one (if flag isn't set or Naming Service was not found). This class also defines the operator-> so that functions like , .. can be called directly on a object, and be forwareded to the root Naming Context. This class is intended to simplify programs that want to play the role of a Naming Service server. To simplify programs that want to play the role of Naming Service clients, use . If a Naming Service is created locally, a TAO_IOR_Multicast event handler is created and installed on the ORB's reactor. This event handler allows other clients on the network to discover and use this Naming Service. Event handler listens on a multicast port for messages from clients looking for a Naming Service, and sends back the ior of the root Naming Context. For more information on how this bootstraping through a multicast process works, check out orbsvcs/orbsvcs/TAO_IOR_Multicast.*, implementation of , and orbsvcs/Naming/README.
