Downcast for servant objects

Hi,
<1> How do I downcast an Object returned by findByProxy to a servant object. For example I am trying the following:

{
Ice::Object object_=adapter_->findByProxy(someproxy);

// now how d i convert this object_ to
// some ServantPtr objectTwo_. In short I am trying to extract a servant given the proxy.
}

<2>On another note, if i have an interface named
iMachine which is implemented by C++ class Machine.

how can iMachinePtr be converted to Machine*.

thanks
bks

To downcast class instances, use:

DerivedClassPtr derived = DerivedClassPtr::dynamicCast(base);

You can downcast to an implementation by using a typedef like this:

typedef IceUtil::Handle<Machine> MachinePtr;

Then use MachinePtr::dynamicCast() as described above.

Marc,
thanks that helped.
