PeerOS

Purpose

The Peer Object Subscriber set of classes help us set up an Observer (aka Publisher-Subscriber) design pattern.

This solves the problem of complex message handling in a large C++ application with many small pieces.

The three classes making up the PeerOS library are:

PeerMessage: Describes ("is a") a message.
PeerPublisher: pushes a message down to the subscribers.
PeerReader: A subscriber. Will only receive messages from a Publisher to which it has subscribed.

A class derived from PeerPublisher to publish Foo messages should be named CMPublish_Foo. The "CMPublish" stands for "Class for Message Publishing."
A class derived from PeerMessage to represent a Foo message should be named CM_Foo.
A class derived from PeerReader to read (aka handle) a Foo message should be named CMRead_Foo.
