Member Function Documentation

ACE_INLINE CORBA::ULong TAO_Target_Specification::iop_ior (  IOP::IOR *&  ior  ) 
 

Returns a pointer to IOP::IOR through the parameters and the index of the selected profile as a return parameter after a check of the stored specifier. If the stored specifier is not of the right type then this would return a NULL.

ACE_INLINE const TAO::ObjectKey * TAO_Target_Specification::object_key (  void   )
