Visualise your Classes Component in the Method Explorer
From the 4D v19 R5, components can publish their classes. This feature came with tips and code completion support to smooth your code writing.
To make your coding experience even easier, 4D v19 R7 is bringing a new feature: say hello to the support of classes in the method explorer.
HTTP classes: A New Way to Perform Asynchronous HTTP Requests
In our constant effort to improve 4D syntax and functionalities, we have decided to bring you new commands to perform HTTP requests in 4D: the HTTP classes. They are available right in 4D v19 R6 and will feature many improvements over the coming versions. Let me show you how to use them right away.
Access your component classes from your host project
Components can now publish classes! And even better, if your application is still in binary mode, you can now benefit from classes and object-oriented development by using a component (in project mode) to create your own classes and use them from your (binary mode based) application.
Tips: ORDA Data Model Classes
By now you’re aware of the availability of ORDA classes. In this blog post, you’ll learn a few handy tips to get the most out of them!
ORDA Data Model Classes and REST
In a previous blog post, you learned about ORDA classes and the possibilities they offer to make your coding experience smoother. In this blog post, you’ll see how to use them with the REST server.
Let’s see it in action!
ORDA Classes to handle your data model
In a previous blog post, we introduced you to the world of ORDA data model classes. Now it’s time to get our hands dirty and learn more!
You already know that ORDA’s structure (datastore, dataclass, entity, entity selection) is made up of objects. But they’re not just objects, they’re strongly-typed objects linked to specific ORDA classes. This means that you can write functions to hide the complexity of your data’s physical implementation.
Welcome to the world of ORDA classes
ORDA was a revolution with 4D v17. It opened a whole new world of possibilities and took you to another programming dimension. A dimension where you can easily develop applications using an object-oriented approach.
We didn’t stop there! We continued to add enhancements to ORDA through a set of features in each subsequent feature release. Now with 4D v18 R4, we’re thrilled to be going another step further with the availability of ORDA data model classes. Classes dedicated to your data model.
This will greatly elevate your code. Your applications can now easily expose services, be more manageable and easier to maintain, and seamlessly integrate with other applications.
This is another big feature made possible thanks to the projects!
An intro to object-oriented programming in 4D: Classes
Many of you have have been asking to be able to define an object type ever since the Object type became available. Thanks to object notation, many of you dream of having object functions. Dream no more and say hello to classes in 4D v18 R3 project database! In this blog post, we’re introducing one of the most interesting concepts of object-oriented programming … along with a database example and a bonus video!
Filter Access to your Data with a Complete System of Permissions
Filter access to data is a must-have feature to prevent malicious access to your application.
So far, you could expose or not expose as a REST resource a dataclass and some of its attributes. It was already a convenient means to restrict access to your data. Still, we’re thrilled to deliver in the v19R8 a powerful and fully customizable system to protect your data from unauthorized users. A system to protect your data depends on who is accessing it and which data is accessed.
