Hands-On Design Patterns with Delphi

By: Primož Gabrijelčič

Overview of this book

Design patterns have proven to be the go-to solution for many common programming scenarios. This book focuses on design patterns applied to the Delphi language. The book will provide you with insights into the language and its capabilities of a runtime library. You'll start by exploring a variety of design patterns and understanding them through real-world examples. This will entail a short explanation of the concept of design patterns and the original set of the 'Gang of Four' patterns, which will help you in structuring your designs efficiently. Next, you'll cover the most important 'anti-patterns' (essentially bad software development practices) to aid you in steering clear of problems during programming. You'll then learn about the eight most important patterns for each creational, structural, and behavioral type. After this, you'll be introduced to the concept of 'concurrency' patterns, which are design patterns specifically related to multithreading and parallel computation. These will enable you to develop and improve an interface between items and harmonize shared memories within threads. Toward the concluding chapters, you'll explore design patterns specific to program design and other categories of patterns that do not fall under the 'design' umbrella. By the end of this book, you'll be able to address common design problems encountered while developing applications and feel confident while building scalable projects.

Chapter 11. Other Kinds of Patterns

In this book, we have discussed design patterns, anti-patterns, idioms, programming techniques, and more, but that barely scratches the surface. There are many other kinds of patterns that we could talk about, and there are many more roads to discover.

I have intentionally stayed away from architectural and enterprise patterns. On the one hand, they are not that interesting to the intended audience of this book programmers while, on the other hand, they really cannot be summarized in a few pages. A very thick book would need to be written to cover these two topics and summarizing them on a few pages would only give them injustice.

Instead of that, I have decided to focus on three concepts that don't fit into our previously covered categories but are still very important to an everyday Delphi programmer. I will discuss exceptions, debugging, and functional programming.

In this chapter, we will cover the following:

  • Learning about exceptions
  • Finding out how exceptions...
