Detailed Description

Defines a wrapper class that holds the root Naming Context.

This class either finds an existing Naming Service (if the <resolve_for_existing_naming_service> flag is set) or creates one (if <resolve_for_existing_naming_service> flag isn't set or Naming Service was not found). This class also defines the operator-> so that <NamingContext> functions like <bind>, <unbind> .. can be called directly on a <TAO_Naming_Server> 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 <TAO_Naming_Client>. 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 <resolve_initial_references>, and orbsvcs/Naming/README.


Constructor & Destructor Documentation

TAO_Naming_Server::TAO_Naming_Server void   ) 
 

Default constructor.

TAO_Naming_Server::TAO_Naming_Server CORBA::ORB_ptr  orb,
PortableServer::POA_ptr  poa,
size_t  context_size = ACE_DEFAULT_MAP_SIZE,
ACE_Time_Value timeout = 0,
int  resolve_for_existing_naming_service = 1,
const ACE_TCHAR persistence_location = 0,

int  enable_multicast = 1,
int  use_storable_context = 0,
int  round_trip_timeout = 0,
int  use_round_trip_timeout = 0
 

Constructor. Attempts to find an existing Naming Service if <resolve_for_existing_naming_service> is set to true. If it is false, or no Naming Service was found during a <timeout> period, create the Naming Service in this process. If creating the Naming Service locally, make the root context of size <context_size>, register it under the <poa>, and make the Naming Service persistent if <persistence_location> is not 0. (<persistence_location> specifies name of the file to use for persistent storage, <base_addr> specifies the address used for memory mapping <persistent_location> file). If <enable_multicast> is not zero then the service will respond to multicast location queries.

TAO_Naming_Server::~TAO_Naming_Server void   ) 
 

Destructor.


Member Function Documentation

int TAO_Naming_Server::fini void   ) 
 

Destroy the child POA created in <init_with_orb>.

size_t  context_size = ACE_DEFAULT_MAP_SIZE,

Initializer. Attempts to find an existing Naming Service if <resolve_for_existing_naming_service> is set to true. If it is false, or no Naming Service was found during a <timeout> period, create the Naming Service in this process. If creating the Naming Service locally, make the root context of size <context_size>, register it under the <poa>, and make the Naming Service persistent if <persistence_location> is not 0. (<persistence_location> specifies name of the file to use for persistent storage, <base_addr> specifies the address used for memory mapping <persistent_location> file). If <enable_multicast> is not zero then the service will respond to multicast location queries.

[protected]
 

Helper method: create Naming Service locally. Make the root context of size <context_size>, register it under the <root_poa>, and make the Naming Service persistent if <persistence_location> is not 0. (<persistence_location> specifies name of the file to use for persistent storage). If <enable_multicast> is not zero then the service will respond to multicast location queries.

int TAO_Naming_Server::init_with_orb int  argc,
ACE_TCHAR argv[],
CORBA::ORB_ptr  orb
 

Initialize the Naming Service with the command line arguments and the ORB.

char * TAO_Naming_Server::naming_service_ior void   ) 
 

Returns the IOR of the naming service.

CosNaming::NamingContext_ptr TAO_Naming_Server::operator-> void   )  const
 

Returns a <NamingContext_ptr> for the root Naming Context.

int TAO_Naming_Server::parse_args int  argc,
ACE_TCHAR argv[]
[protected]
 

parses the arguments.
