AW: [omniORB] Usage of _out objects

[Fischer, Clemens]

Hi,
you should use the out() method of type A_var like this:

A_var a;
server->f(a.out());

A_var does the memory management...

Betreff: [omniORB] Usage of _out objects

Say you are calling this function from the client (c++):

void Server::f(A_out a){
...
}

How do you set the A_out (variable length) object?

My book says it's a "reference to a pointer". I'm not sure what that is
and not how to handle them.

And if I understand my book correct, I don't need to free/release the
object on the server (callee) side. Is this correct?


Sorry for the stupid question, but I'm new to CORBA...

Should have read your question completely.
On the server side you have to allocate memory for the out parameter:

void Server::f(A_out a){
...
a = new A();
...
}

That gives me
error: no match for 'operator=' in a ...

A is an interface in my idl.
Does that mean that I need to activate the object in the POA to get a
reference?
