NAME

6       orber_ifr  -  The  Interface  Repository  stores representations of IDL
7       information
8

DESCRIPTION

10       This module contains functions for managing  the  Interface  Repository
11       (IFR).  This documentation should be used in conjunction with the docu‐
12       mentation in chapter 6 of 2.3. Whenever the term IFR object is used  in
13       this  manual  page, it refers to a pseudo object used only for interac‐
14       tion with the IFR rather than a CORBA object.
15

INITIALIZATION OF THE IFR

17       The following functions are used to initialize the Interface Repository
18       and to obtain the initial reference to the repository.
19

EXPORTS

21       init(Nodes,Timeout) -> ok
22
23              Types:
24
25                 Nodes = list()
26                 Timeout = integer() | infinity
27
28              This function should be called to initialize the IFR. It creates
29              the necessary mnesia-tables. A mnesia schema should  exist,  and
30              mnesia must be running.
31
32       find_repository() -> #IFR_Repository_objref
33
34              Find the IFR object reference for the Repository. This reference
35              should be used when adding objects to the IFR, and when extract‐
36              ing  information  from  the IFR. The first time this function is
37              called, it will create the repository and all the primitive def‐
38              initions.
39

GENERAL METHODS

41       The  following functions are the methods of the IFR. The first argument
42       is always an #IFR_objref, i.e. the IFR (pseudo)object on which to apply
43       this  method. These functions are useful when the type of IFR object is
44       not know, but they are somewhat  slower  than  the  specific  functions
45       listed  below  which only accept a particular type of IFR object as the
46       first argument.
