Part 1. Introduction
1 The path to well-designed software
1.1 What is software design?1.2 What you will learn from this book1.3 The benefits of good software design1.4 A few design examples1.4.1 Leaking changes1.4.2 Code that’s too complex1.4.3 Inflexible code1.4.4 Surprise!1.4.5 Common architecture problems1.5 Make sure we’re going to build the right application; then, build it right1.6 Good design doesn’t come easily1.7 Change and complexity are the enemies of good design1.8 Design with object-oriented programming conceptsSummary

12 The Observer Design Pattern

This chapter covers

The Observer Design Pattern

In this chapter, we continue with the theme of sports reports generated by a college athletics department. The Observer Design Pattern supports the publisher–subscriber model, where one component creates data objects that subscriber components process individually, each in its own way. The publisher component doesn’t know how the subscriber components are implemented nor does it care what the subscribers do with the data.

Our example application monitors the progress of a baseball game. It prints game statistics both while the game is in progress and after it is over.

NOTE Be sure to read the introduction to part 4 for important information about design patterns ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
