[omniORB] sequence<interface>

[David Riddoch]

That sounds roughly correct, but I'm not sure what you mean by
seq_of_A::duplicate().

Here's an outline of how I think it should be coded ...

Server side:
============
seq_of_A* B::getAseq()
{
  seq_of_A* s = new seq_of_A;
  seq_of_A& seq = *s;

  seq.length(2);

  A_impl* a = new A_impl(whatever ...);
  a->_obj_is_ready(boa);
  seq[0] = a->_this();

  a = new A_impl(another one ...);
  a->_obj_is_ready(boa);
  seq[1] = a->_this();

  return s;
}

Client side:
============
void f(B_ptr b)
{
  seq_of_A* s = b->getAseq();
  seq_of_A& seq = *s;

  s[0]->do_something();

  ...

  delete s;
}
