Delphi Generic Collections

Covering all the containers available in the collections library

   Watch Promo

The Generic Collections Library is one of the best recent additions to the Delphi RTL. With it you can get type safety on your containers without having to write a whole bunch of boiler plate code each time. This can represent a big reduction in the amount of code you need write and also reduce bugs in your code. Learn how to best make use of this library and take advantage of some of its more powerful features.

This video covers all the containers available in the collections library and gives an in depth account of most of their capabilities. You will learn about the basic containers (TStack, TQueue and TList), covering their basic features (adding, moving, removing etc.) then more advanced topics such as how the internals of sorting works. Then we move on to TDictionary and how hashing works and how you can provide your own hashing mechanisms to changes its default behavour. Finally we look at the thread safe collections and how they can be used in multi-threaded code.

I have been programming in Delphi since 1999, primarily building and maintaining applications for the real estate, banking and legal industries here in New Zealand, in these roles I have also used other technologies such a C#, Ruby on Rails, Android/Java, but Delphi is my favorite environment. I have presented at numerous online CodeRage conferences, these conferences last for an entire week with thousands of participants (the replays for all of my presentations are available on this site), and I was an international guest speaker at ADUG in 2013. Most of my videos also appear on YouTube, for which I have over a million views, and over five thousand subscribers.

In 2012 Embarcadero invited me to join a select group of Delphi experts from around the world to form the Embarcadero MVP program, to which fewer than 100 people worldwide have been admitted (I'm the only one from New Zealand).

I also play guitar, invest in real estate, regularly work out at the gym, and of course maintain the LearnDelphi.tv courses.
