MODULE SUMMARY

The Interface Repository stores representations of IDL information

DESCRIPTION

This module contains functions for managing the Interface Repository (IFR). This documentation should be used in conjunction with the documentation in chapter 6 of CORBA2.3. Whenever the term IFR object is used in this manual page, it refers to a pseudo object used only for interaction with the IFR rather than a CORBA object.

Initialization of the IFR

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

EXPORTS

init(Nodes,Timeout) -> ok

Types:

Nodes = list()

Timeout = integer() | infinity

This function should be called to initialize the IFR. It creates the necessary mnesia-tables. A mnesia schema should exist, and mnesia must be running.

find_repository() -> #IFR_Repository_objref

Find the IFR object reference for the Repository. This reference should be used when adding objects to the IFR, and when extracting information from the IFR. The first time this function is called, it will create the repository and all the primitive definitions.

General methods

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