Passing implementation objects as parameters

[cuaji]

I'd like to pass an object as parameter. For example, If I make this interface:

/////////////////////////////////////////////
//Define the MyClass class
#include "myclass.idl"

interface sample
{
void MyFunction(in MyClass my_object);
}
/////////////////////////////////////////////

, the generated code for the function looks like this:

void sample::MyFunction(MyClass_ptr my_object);

However, I needn't a MyClass_ptr (pointer to MyClass) type parameter; I would like
a MyClass_i (implementation) parameter, because my code is added on the implementation class.

How can I solve this?

Finally, I need the same function but with out-parameters (out MyClass in this case).

Thanx,
