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 <NamingContext> functions like <resolve>, etc. can be directly called on a <TAO_Naming_Client> 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 <_duplicate> so that it can be stored into a <*_var>.

Definition at line 20 of file Naming_Client.cpp.

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

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

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

Definition at line 27 of file Naming_Client.cpp.
