[omniORB] How to convert an object reference to a servant?

[Tim Theisen]

In the example given below.  You can easily call getBalance() with the
Account_ptr.
 
double balance = account->getBalance();
 
I don't see any need to get an Account_I *.

Since I didn't make myself very clear in the topic, let me give you an
example this time.  Consider this IDL,

interface Account {
    double getBalance();
    ...
};

interface BankManager {
    Account getAccount( in string name );

    void deleteAccount( in account);
};

The implementation that I'm having trouble with is deleteAccount().  The
C++ code looks something like this,

void BankManager_I::deleteAccount( Account_ptr account )
{
    //
    // Here I want to access the "account" implementation.  How do I do
it?
    // Somehow I will need to convert Account_ptr to (Account_I *)
    //
    Account_I *account_i;
    .....
}

As you can see in the code above, I would like to be able to get access
to the implementation of the "account" object, passed in from the
client.  How do I do that?  Orbix provides the _deref() function to do
this, and I'm hoping there is a way to do it in omniORB, but so far I'm
not successful.  Is this an unusual case for the IDL, ie. you shouldn't
allow clients to pass in an object reference as a parameter?

Thanks again for any information that you can provide,
Tuyen
