The Hierarchical Key
Mantra: Manage recursion, not complexity.
Tagline: One structure, infinite depths.
wor_Recursive provides a robust recursive qualifier manager that handles hierarchical data with elegance and simplicity. It offers full ORDA support for both Integer and UUID primary keys, transforming the management of tree‑like structures into an intuitive workflow.
- Full ORDA Support: Seamlessly manage hierarchical data with complete ORDA integration. Works natively with both Integer and UUID primary keys for maximum flexibility.
- Recursive Qualifier Manager: A powerful system dedicated to handling qualifiers with unlimited depth, providing a standardized way to navigate and manipulate hierarchical structures.
- Developer‑Centric Design: Built to eliminate the boilerplate code typically required for tree structures, allowing you to focus on your application's unique business logic.
- Multi‑Language Support: Fully localized in English (EN), French (FR), Spanish (ES), and German (DE).
- 4DPop toolbar Compatible. It includes a 4DPop.json manifest for easy integration.
- 4D 21 or higher (Project mode recommended).
- wok_Krolific – Licensing component (mandatory dependency).
- wox_Xlibrary – Core utilities (mandatory dependency).
- woc_Colours – Color management engine (mandatory dependency).
- waz_Wazar – UI widgets (mandatory dependency).
- The 4D SVG component must be available in your project.
Starting with 4D 21, the recommended way to install wor_Recursive (and any ogTools component) is through the Dependencies Manager using the GitHub repository:
- In your 4D project, open the Dependencies Manager (
Project > Dependencies). - Click the
+button and select Add a dependency from a Git URL. - Enter the following Git URL:
protee/wor_Recursive - Choose the desired version (e.g.,
main,latest, or a specific release tag). - Confirm the installation – the component will be automatically fetched from GitHub, and linked to your project.
- Don't forget to open your database structure settings dialog and go to the Security page to enable, if necessary, the Execute the "On host database event" method of the component option. This ensure your component is well initialised automatically.
Note: For team development, commit the dependency configuration file (
dependencies.json) to your source control so all team members automatically fetch the same version from GitHub.
