Copland: Applications
built 650 days ago
Copland helps you tie the pieces of your application together. Instead of inter-object relationships and dependencies being specified in the code, you feed them into Copland. This makes those relationships easier to modify, since you never have to modify the source code to change them.

As mentioned earlier, applications under Copland will be able to create tasks that are preemptively scheduled. You'll be able to assign priorities to your preemptive tasks, but this in itself won't prevent the tasks from preempting each other at inopportune times. What you'll need in order to ensure correct behavior from your tasks is a mechanism to synchronize access to shared resources.

Your object is still just a plain ol’ ordinary Ruby object, but Copland has effectively transformed it into a singleton. This means you can unit test it as if it were nothing special, but when it is used in your application it will act like a singleton.

Note ... that Open Transport, which is now available for development on System 7.5, will be the native networking protocol in Copland. Applications that use it will make best use of the native networking stack and will be prepared to run in a separate address space.
