# Documentation: PedestrianAndHeadReportsModule

## 1. Purpose

This module is a Prism-based module responsible for registering pedestrian and head report components within the application's Unity dependency injection container. It serves as the entry point for the `PedestrianAndHeadReports` feature area, registering input/output views and their corresponding view models for head reports and TRL (Transport Research Laboratory) reports. The module also provides assembly metadata via a custom attribute for display on the main screen.

---

## 2. Public Interface

### `PedestrianAndHeadReportsModule` Class

A Prism module implementation that registers views and view models with the Unity container.

**Constructor:**
```csharp
public PedestrianAndHeadReportsModule(IUnityContainer unityContainer)
```
- Accepts an `IUnityContainer` instance via dependency injection and stores it in a readonly field `_unityContainer`.

**Method:**
```csharp
public void Initialize()
```
- Registers the following type mappings with the Unity container:
  - `IHeadReportInputView` → `HeadReportInputView`
  - `IHeadReportOutputView` → `HeadReportOutputView`
  - `IHeadReportViewModel` → `HeadReportViewModel`
  - `ITRLReportInputView` → `TRLReportInputView`
  - `ITRLReportOutputView` → `TRLReportOutputView`
  - `ITRLReportViewModel` → `TRLReportViewModel`

---

### `PedestrianAndHeadReportsImageAttribute` Class

An attribute class extending `ImageAttribute` that provides assembly metadata for display in the application's main screen.

**Constructor:**
```csharp
public PedestrianAndHeadReportsImageAttribute()
public PedestrianAndHeadReportsImageAttribute(string s)
```
- Parameterless constructor chains to the string overload with `null`.
- The string parameter `s` is accepted but not used in the implementation.

**Properties:**

| Property | Return Type | Implementation |
|----------|-------------|----------------|
| `AssemblyImage` | `BitmapImage` | Returns image from `AssemblyInfo.GetImage(AssemblyNames.DB.ToString())` |
| `AssemblyName` | `string` | Returns `AssemblyNames.PowerAndBattery.ToString()` |
| `AssemblyGroup` | `string` | Returns `eAssemblyGroups.Administrative.ToString()` |
| `AssemblyRegion` | `eAssemblyRegion` | Throws `NotImplementedException` |

**Methods:**

| Method | Return Type | Implementation |
|--------|-------------|----------------|
| `GetAttributeType()` | `Type` | Returns `typeof(ImageAttribute)` |
| `GetAssemblyImage()` | `BitmapImage` | Returns `AssemblyImage` property |
| `GetAssemblyName()` | `string` | Returns `AssemblyName` property |
| `GetAssemblyGroup()` | `string` | Returns `AssemblyGroup` property |
| `GetAssemblyRegion()` | `eAssemblyRegion` | Throws `NotImplementedException` |

## 3. Invariants

- The `_unityContainer` field is `readonly` and must be provided at construction time.
- The `Initialize()` method must be called for any views or view models in this module to be res
