Delphi Cookbook - Third Edition

By: Daniele Spinetti, Daniele Teti

Overview of this book

Delphi is a cross-platform integrated development environment (IDE) that supports rapid application development on different platforms, saving you the pain of wandering amid GUI widget details or having to tackle inter-platform incompatibilities. Delphi Cookbook begins with the basics of Delphi and gets you acquainted with JSON format strings, XSLT transformations, Unicode encodings, and various types of streams. You’ll then move on to more advanced topics such as developing higher-order functions and using enumerators and run-time type information (RTTI). As you make your way through the chapters, you’ll understand Delphi RTL functions, use FireMonkey in a VCL application, and cover topics such as multithreading, using aparallel programming library and deploying Delphi on a server. You’ll take a look at the new feature of WebBroker Apache modules, join the mobile revolution with FireMonkey, and learn to build data-driven mobile user interfaces using the FireDAC database access framework. This book will also show you how to integrate your apps with Internet of Things (IoT). By the end of the book, you will have become proficient in Delphi by exploring its different aspects such as building cross-platforms and mobile applications, designing server-side programs, and integrating these programs with IoT.

Serializing objects to JSON and back using RTTI

When you are using a domain model pattern (and you should do most of the time for non-trivial applications), the entities managed by your program are contained in objects. An object has a state and methods to change its state, just like any actual object in the real world.

Getting ready

Just like the datasets in the previous recipe, the need to serialize an object in a JSON object, send the object somewhere, and then recreate that object as it was before is very common. In this recipe, we'll use the TJson class and extend it with new functionalities.
