ObserverClass Observer Class for LabVIEW A lightweight, flexible implementation of the Observer Pattern designed for LabVIEW applications. This class allows any number of observers to register to one or more observable data sources and get automatically updated whenever the data changes—promoting clean, modular, decoupled architecture.

✨ Features

Simple, class-based implementation of the classic Observer Pattern Supports multiple observers registered to multiple observables Automatic update propagation via the NotifyObserver method Ideal for UI updates, modular architectures, plugin systems, data monitoring, and event‑driven applications

📦 Installation Requirements To use this library, you need: LabVIEW 2025 Q3

🔧 LabVIEW Composition Toolkit (PNR) This library is required because it provides utilities to compose and decompose LabVIEW data types. You can install it via VIPM:

Name: LabVIEW Composition Toolkit Publisher: PNR VIPM Page: https://www.vipm.io/package/pnr_lib_labview_composition/ [vipm.io] Description: Provides functions to compose and decompose objects, clusters, maps, and sets in LabVIEW. Useful when interacting with class data structures. [vipm.io]

📁 Included Example A full working example is included in the project: Example This example demonstrates: Two independent Observer instances Each registered to its own observable data source Automatic updates triggered through NotifyObserver

Perfect as a starting point to understand how to integrate the class into your own applications.

🚀 How to Use Here’s a minimal usage workflow:

Create an Observer instance Register it to one or more observable data points Trigger an update using the NotifyObserver method The observer receives data and executes its update logic

Example visual workflow:

🧩 Extending the Class You can easily:

Override the Observer update method Add custom observable types Integrate the Observer class into plugin architectures or messaging systems Chain multiple observables for complex update flows
