# SensorSettingsModule

### **1. Purpose**  
This module, named `SensorSettingsModule`, is a Prism-based modular component responsible for registering the view and view model for the sensor settings UI within a modular WPF application. It integrates with the Unity dependency injection container to expose `ISensorSettingsView` and `ISensorSettingsViewModel` as singleton services, enabling the main application shell to display and manage sensor configuration UI. It also contributes metadata (name, image, group, region) to the host application’s module discovery and UI assembly system via custom assembly-level attributes.

---

### **2. Public Interface**

#### **`SensorSettingsModuleModule` class**
- **`public SensorSettingsModuleModule(IUnityContainer unityContainer)`**  
  Constructor that receives the Unity container via dependency injection. Stores the container for later use in type registration.

- **`public void Initialize()`**  
  Registers the following types as singletons in the Unity container:  
  - `ISensorSettingsView` → `SensorSettingsView`  
  - `ISensorSettingsViewModel` → `SensorSettingsViewModel`  
  This method is called both directly by the constructor’s usage pattern (via `RegisterTypes`) and by Prism’s module initialization pipeline.

- **`public void OnInitialized(IContainerProvider containerProvider)`**  
  Currently empty; no logic is executed during Prism’s `OnInitialized` phase.

- **`public void RegisterTypes(IContainerRegistry containerRegistry)`**  
  Delegates to `Initialize()` (despite using a different container interface, `IContainerRegistry`, the method still invokes the internal `Initialize()` that uses `_unityContainer`). *Note: This may indicate a potential inconsistency, as `containerRegistry` is unused.*

#### **`[assembly: SensorSettingsModuleModuleName]`**
- **`SensorSettingsModuleModuleNameAttribute` class**  
  - **`public override string AssemblyName { get; }`**  
    Returns `"SensorSettingsModule"` (via `AssemblyNames.SensorSettingsModule.ToString()`).  
  - **`public override Type GetAttributeType()`**  
    Returns `typeof(TextAttribute)`.  
  - **`public override string GetAssemblyName()`**  
    Returns the value of `AssemblyName`.  

#### **`[assembly: SensorSettingsModuleModuleImageAttribute]`**
- **`SensorSettingsModuleModuleImageAttribute` class**  
  - **`public override BitmapImage AssemblyImage { get; }`**  
    Returns a `BitmapImage` loaded via `AssemblyInfo.GetImage("SensorSettingsModule")`.  
  - **`public override string AssemblyName { get; }`**  
    Returns `"SensorSettingsModule"`.  
  - **`public override string AssemblyGroup { get; }`**  
    Returns `"Administrative"` (via `eAssemblyGroups.Administrative.ToString()`).  
  - **`public override eAssemblyRegion AssemblyRegion { get; }`**  
    Returns `eAssemblyRegion.SensorSettingsModuleRegion`.  
  - **`public override Type GetAttributeType()`**  
    Returns `typeof(ImageAttribute)`.  
  - **`public override BitmapImage GetAssemblyImage()` / `GetAssemblyName()` / `GetAssemblyGroup()` / `GetAssemblyRegion()`**  
    Delegate to their respective properties.

### **3. Invariants**
- The module **must** be loaded into a Prism-based application using Unity as the DI container.
- `ISensorSettingsView` and `ISensorSettingsViewModel` are registered as **singletons** (per container lifetime).
- The `AssemblyName` for this module is strictly `"SensorSettingsModule"` (derived from `AssemblyNames.SensorSettingsModule` enum).
- The module belongs to the `"Administrative"` group (`eAssemblyGroups.Administrative`) and is assigned to `eAssemblyRegion.SensorSettingsModuleRegion`.
- The module image is loaded from a static `AssemblyInfo.GetImage(...)` method, implying a fixed image resource naming convention (`"SensorSettingsModule"`).

### **4. Dependencies**
#### **Imports / External Dependencies**
- **Prism.Modularity** (`IModule`, `ModuleAttribute`) — for module lifecycle integration.
- **Unity** (`IUnityContainer`, `IContainerRegistry`) — for DI container access.
- **DTS.Common** and **DTS.Common.Interface** — defines core contracts:
  - `ISensorSettingsView`, `ISensorSettingsViewModel` (from `DTS.Common.Interface.Sensors.SensorSettingsModule`)
  - `AssemblyNames`, `AssemblyInfo`, `eAssemblyGroups`, `eAssemblyRegion`, `TextAttribute`, `ImageAttribute` — used by attributes.
- **System.Windows.Media.Imaging** — for `BitmapImage` type.

#### **Depended Upon**
- The host application (via Prism’s module catalog) depends on this module to provide sensor settings UI.
- Other modules or views may depend on `ISensorSettingsView`/`ISensorSettingsViewModel` being registered (e.g., to inject or navigate to the view).

---

### **5. Gotchas**
- **`RegisterTypes` uses `IContainerRegistry` but calls `Initialize()` which uses `_unityContainer` (of type `IUnityContainer`)** — this may cause confusion or runtime issues if `IContainerRegistry` is not internally backed by the same Unity container instance. The `containerRegistry` parameter is unused.
- **`OnInitialized` is empty** — if future logic is added here, it must be compatible with Prism’s module initialization order.
- **Assembly-level attributes are applied unconditionally** — their behavior relies on `AssemblyNames.SensorSettingsModule` and `AssemblyInfo.GetImage(...)` being correctly defined elsewhere in `DTS.Common`.
- **No validation or error handling is visible** — if `AssemblyInfo.GetImage(...)` fails (e.g., missing image resource), the attribute constructor may throw silently or return null (behavior depends on `AssemblyInfo` implementation).
- **No public API beyond module registration** — this module does not expose domain logic; it only bootstraps UI components.
