Distributed class instances

Hi,

if there is a class instance passed to one or more clients, may each client change class attributes (are attributes public?) ? Are changes of class attributes distributed to all hosts holding the instance? E.g. as example of calls by reference, there is linked list using classes in Ice-Doc. What happens if server or client add/remove list members? Who will be informed...

Thanks & Bye
Matthias

    Hi Matthias,

    When you pass class instances "by value", you just pass copies of the data. When a recipient changes its copy of a class instance, it's a purely local operation -- other copies are not affected or notified.

    You can also give your clients proxies to an object that implements a Slice class. In this case, the clients can only access the class operations (as if the object implements just an interface).

    Hope this helps!
    Bernard
