I want to do this (no particular language): print(foo.objects.bookdb.books[12].title); or this: book = foo.objects.bookdb.book.new();

I want to do this (no particular language):

print(foo.objects.bookdb.books[12].title);

or this:

book = foo.objects.bookdb.book.new(); book.title = 'RPC for Dummies'; book.save();

Where foo actually is a service connected to my program via some IPC, and to access its methods and objects, some layer actually sends and receives messages over the network.

Now, I’m not really looking for an IPC mechanism, as there are plenty to choose from. It’s likely not to be XML based, but rather s. th. like Google’s protocol buffers, dbus or CORBA. What I’m unsure about is how to structure the application so I can access the IPC just like I would any object.

In other words, how can I have OOP that maps transparently over process boundaries?

Not that this is a design question and I’m still working at a pretty high level of the overall architecture. So I’m pretty agnostic yet about which language this is going to be in. C#, Java and Python are all likely to get used, though.

  1. You shouldn’t do it! It is very important for programmers to see and feel the difference between an IPC/RPC and a local method call in the code. If you make it so, that they don’t have to think about it, they won’t think about it, and that will lead to very poorly performing code.

    Think of:

    foreach o, o.isGreen in someList {     o.makeBlue;  }

    The programmer assumes that the loops takes a few nanoseconds to complete, instead it takes close to a second if someList happens to be remote.
