[omniORB] Is it possible to narrow to a local implementation?

[Ramón Talavera]

I hope this does not sound too weird or basic.

Is it possible to 'narrow' a _ptr or _var instance to a concrete
implementation, I mean, obtain the real implementation of the
wrapped-around-by-corba so that I communicate with it through the 'local'
interface?

For example:

AImp is-a CorbaObject that implements CA , it contains a public method mX()
NOT present in the IDL.

AImp *a=new AImp(ORB);
a.mX(); // perfectly possible due to being AImp


... later, in another method, and in the same machine:

CA_ptr ca= get a corba reference to a by narrowing.
ca.mX(); // illegal, mX() is not part of the IDL

AImp *a=(AImp*) (ca->_get_Implementation()); // cannot make this to compile


Is _get_Implementation() suppossed to do what I am trying to archieve? Is
it even possible to access the real wrapped implementation when local to
the object?

Thanks in advance.

Hi Ram?n,

This only makes sense within the same process that hosts the CORBA object. It can be done by calling a method of the POA called reference_to_servant.

Regards,
Luke.
