[omniORB] Help for a beginner

[Michael]

Hello Michel,

I would suggest reading a book about CORBA (this is not omniORB specific).

In general, there are no constructors in CORBA (remember, the I in IDL
means Interface) - instead you'll have to use the factory pattern.

A possible similar effect of an interface that represents your example is:

module Test
{
  interface A
  {
    void foo();
  };

  interface B: A
  {
    void doSomething();
  };

  interface BFactory
  {
    B createB(in Test::A a);
  };
};

The implementation would include the followin:
- Implementation of BFactory (normally a singleton)
- Implementation of B
- Implementation of A
- A main that initializes the ORB, creates POAs, registers BFactory
  in a well-known place (e.g. using the naming service), so clients
  can factor objects of type B and starts up the orb. Since you're
  only passing around object references the question here would be
  where to get object references of A (besides nil references).

In the end, try to get a copy of "Advanced CORBA Programming with C++"
to understand what CORBA is about.

cheers
