4D Coding #03 – Objects and collections
In a very short space of time, objects have become an essential part of the 4D language and form the basis of ORDA’s capabilities. In this course, we’ll take a look at the capabilities of objects (and collections), and tell you a little more about how they’re used and how they work internally.
Features
- Detailed understanding of objects: references, behaviors, object notation
- Introduction to ref counting and automatic memory management
- Collection management: iteration, transformation, search
- Clear comparison: arrays vs. collections
- Discover Storage and its uses
- Essential foundations for linking up with classes and ORDA
Target audiences
- Intermediate or experienced 4D developers
- Developers who have used objects/collections and want to better understand their inner workings
Requirements
- Basic knowledge of 4D language
Curriculum

- Object basicsIn this section of 4 lessons, we'll discover or rediscover the foundations of objects, starting with the essentials.4
- The collectionsThe collections are both similar and very different from the objects. This deserves a dedicated section!2
- Sharing is a pleasureBeing able to share objects and collections opens up a whole new perspective on our code.4
