Mastering Delphi Programming: A Complete Reference Guide

By: Primož Gabrijelčič

Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for most operating systems, including Microsoft Windows, iOS, and now Linux with RAD Studio 10.2. If you know how to use the features of Delphi, you can easily create scalable applications in no time. This Learning Path begins by explaining how to find performance bottlenecks and apply the correct algorithm to fix them. You'll brush up on tricks, techniques, and best practices to solve common design and architectural challenges. Then, you'll see how to leverage external libraries to write better-performing programs. You'll also learn about the eight most important patterns that'll enable you to develop and improve the interface between items and harmonize shared memories within threads. As you progress, you'll also delve into improving the performance of your code and mastering cross-platform RTL improvements. By the end of this Learning Path, you'll be able to address common design problems and feel confident while building scalable projects. This Learning Path includes content from the following Packt products: Delphi High Performance by Primož Gabrijel?i? Hands-On Design Patterns with Delphi by Primož Gabrijel?i?

Gang of Four started it all

The design pattern movement (as it applies to programming) was started by the Gang of Four. By Gang of Four, we don't mean the Chinese Cultural Revolution leaders from the seventies or a post-punk group from Leeds, but four authors of a prominent book: Design Patterns: Elements of Reusable Object-Oriented Software. This book, written by Erich Gamma, Richard Helm, Ralph Johson, and John Vlissides, was published in 1994, and thoroughly shook the programming community.

Back in 1994, when C++ was becoming more and more prominent, object orientation was all the rage, and people were programming in Smalltalk. Programmers were simply not thinking in terms of patterns. Every good programmer, of course, had their own book of recipes that work, but they were not sharing them or trying to describe them in a formal way. The GoF book, as it is mostly...
