About Classes as Unions

the .ice file is
class base
{
int d;
};
class stringbase extends base
{
string s;
};
class Hello
{
nonmutating void sayHello(base i);
idempotent void shutdown();
};
....
In the implement file , in the function
void sayHello(base i);
How can I dynamic_cast or static_cast the base pointer to stringbase pointer?

In C++, you can use the smart pointer dynamicCast method:
void sayHello(basePtr i) { stringbasePtr s = stringbasePtr::dynamicCast(i); }
In Java, you can just do a regular dynamic cast:void sayHello(base i) { stringbase s = (stringbase)i; }
