Detailed Description

This class is intended to simplify programs that want to play the role of Naming Service clients.

Wrapper class that locates the root Naming Context. It also defines the operator-> so that functions like , etc. can be directly called on a object, and will be forwarded to the root Naming Context.

Member Function Documentation

CosNaming::NamingContext_ptr TAO_Naming_Client::get_context (  void   )  const
 

Returns a pointer to the root Naming Context. This ptr is duplicated via so that it can be stored into a <*_var>.

Definition at line 20 of file Naming_Client.cpp. 

00021 {
00022   // Must duplicate this pointer so it can be stored in a _var.
00023   return CosNaming::NamingContext::_duplicate (this->naming_context_.in ());
00024 }

int TAO_Naming_Client::init (  CORBA::ORB_ptr  orb,
ACE_Time_Value *  timeout = 0
) 
 

Look for a Naming Service for a period of using . Return 0 if Naming Service is successfully located, and -1 on failure.
