On messages and message-passing

Over the decades, numerous software system architectures have emerged which require invocations across subsystems to be done via message-passing instead of programmatic interface method calls. Such architectures are so common that many programmers have come to regard message-passing as an end in and of itself, oblivious of the fact that it is nothing but a (poor) technical mechanism for accomplishing a certain architectural goal.

Abstract

A mechanism is described for automatically converting method invocations of any programmatic interface into a single-method normal form and converting back to invocations of the original interface, so that general-purpose operations can be performed on the normal form without explicit knowledge of the interface being invoked. Implementations are provided for C# and for Java.
