Delphi High Performance

By: Primož Gabrijelčič

Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for Microsoft Windows, Apple Mac OS X, Google Android, iOS, and now Linux with RAD Studio 10.2. This book will be your guide to build efficient high performance applications with Delphi. The book begins by explaining how to find performance bottlenecks and apply the correct algorithm to fix them. It will teach you how to improve your algorithms before taking you through parallel programming. You’ll then explore various tools to build highly concurrent applications. After that, you’ll delve into improving the performance of your code and master cross-platform RTL improvements. Finally, we’ll go through memory management with Delphi and you’ll see how to leverage several external libraries to write better performing programs. By the end of the book, you’ll have the knowledge to create high performance applications with Delphi.

Chapter 6. Working with Parallel Tools

After using one whole chapter to warn you about the traps of parallel programming, it is now finally time to write some code! Although I always prefer using modern multithreading approaches—and we'll spend all of the next chapter learning them—it is also good to know the basics. Because of that, I have dedicated this chapter to the good old TThread class.

In this chapter, we will cover the following topics:

  • How can you use TThread to write multithreading code?
  • What different approaches to thread management does TThread support?
  • How can exceptions in threads be handled?
  • Which additional functions does TThread implement?
  • How can we implement a communication channel sending messages to a thread?
  • How can we centralize thread-message handling in the owner form?
  • How can we simplify thread writing to the max by implementing a specific framework for one usage pattern?
