# Documentation: PSDReportSettingsModule

## 1. Purpose
This module serves as the entry point for the "PSD Report Settings" feature within the DTS Viewer application. It is a Prism Module (`PSDReportSettingsModule`) responsible for registering its associated View, ViewModel, and Model dependencies with the Unity dependency injection container. Additionally, it defines assembly-level attributes to expose metadata (name, image, grouping, and region) to the main application shell, allowing the module to be discovered and displayed in the UI as an available component.

## 2. Public Interface

### Classes

**`PSDReportSettingsModule`**
Inherits from: `IModule`
*   `PSDReportSettingsModule(IUnityContainer unityContainer)`: Constructor that accepts a `IUnityContainer` instance and stores it in a readonly field.
*   `void RegisterTypes(IContainerRegistry containerRegistry)`: Implements `IModule.RegisterTypes`. Executes the `Initialize()` method to register types with the container.
*   `void OnInitialized(IContainerProvider containerProvider)`: Implements `IModule.OnInitialized`. Currently contains no implementation logic.
*   `void Initialize()`: Registers the following interface-to-concrete-type mappings using the injected `_unityContainer`:
    *   `IPSDReportSettingsViewModel` → `PSDReportSettingsViewModel`
    *   `IPSDReportSettingsModel` → `PSDReportSettingsModel`
    *   `IPSDReportSettingsView` → `PSDReportSettingsView`

**`PSDReportSettingsModuleNameAttribute`**
Inherits from: `TextAttribute`
*   `[AttributeUsage(AttributeTargets.Assembly, AllowMultiple = false)]`
*   `PSDReportSettingsModuleNameAttribute()`: Default constructor.
*   `PSDReportSettingsModuleNameAttribute(string s)`: Overloaded constructor (parameter `s` is unused).
*   `string AssemblyName { get; }`: Overrides the base property. Returns the string representation of `AssemblyNames.PSDReportSettings`.
*   `Type GetAttributeType()`: Returns `typeof(TextAttribute)`.
*   `string GetAssemblyName()`: Returns the value of the `AssemblyName` property.

**`PSDReportSettingsModuleImageAttribute`**
Inherits from: `ImageAttribute`
*   `[AttributeUsage(AttributeTargets.Assembly, AllowMultiple = false)]`
*   `PSDReportSettingsModuleImageAttribute()`: Default constructor.
*   `PSDReportSettingsModuleImageAttribute(string s)`: Overloaded constructor (parameter `s` is unused).
*   `BitmapImage AssemblyImage { get; }`: Returns a `BitmapImage` retrieved via `AssemblyInfo.GetImage(AssemblyNames.PSDReportSettings.ToString())`.
*   `string AssemblyName { get; }`: Returns the string representation of `AssemblyNames.PSDReportSettings`.
*   `string AssemblyGroup { get; }`: Returns `eAssemblyGroups.Viewer.ToString()`.
*   `eAssemblyRegion AssemblyRegion { get; }`: Returns `eAssemblyRegion.PSDReportSettingsRegion`.
*   `Type GetAttributeType()`: Returns `typeof(ImageAttribute)`.
*   `BitmapImage GetAssemblyImage()`: Returns `AssemblyImage`.
*   `string GetAssemblyName()`: Returns `AssemblyName`.
*   `string GetAssemblyGroup()`: Returns `AssemblyGroup`.
*   `eAssemblyRegion GetAssemblyRegion()`: Returns `AssemblyRegion`.

## 3. Invariants
*   **Module Name:** The module is identified by the string `"PSDReportSettings"` in the `[Module]` attribute.
*   **Assembly Group:** The module belongs to the `Viewer` assembly group (defined by `eAssemblyGroups.Viewer`).
*   **Region:** The module is associated with the `PSDReportSettingsRegion` (defined by `eAssemblyRegion.PSDReportSettingsRegion`).
*   **Registration:** The types `IPSDReportSettingsViewModel`, `IPSDReportSettingsModel`, and `IPSDReportSettingsView` are registered with the Unity container as transient types (default `RegisterType` behavior) upon module initialization.

## 4. Dependencies

**Internal Dependencies (referenced types):**
*   `DTS.Common`: Uses `AssemblyNames` enum.
*   `DTS.Common.Interface`: Uses `TextAttribute`, `ImageAttribute`, `eAssemblyGroups`, `eAssemblyRegion`. Also implies the existence of `IPSDReportSettingsViewModel`, `IPSDReportSettingsModel`, and `IPSDReportSettingsView` interfaces.
*   `DTS.Viewer.PSDReportSettings`: Uses `PSDReportSettingsViewModel`, `PSDReportSettingsModel`, `PSDReportSettingsView` concrete classes and `AssemblyInfo` static class.

**External Frameworks:**
*   `Prism.Ioc`: Uses `IContainerProvider`, `IContainerRegistry`.
*   `Prism.Modularity`: Uses `IModule`, `ModuleAttribute`.
*   `Unity`: Uses `IUnityContainer`.
*   `System.Windows.Media.Imaging`: Uses `BitmapImage`.

## 5. Gotchas
*   **Ignored Constructor Parameters:** Both `PSDReportSettingsModuleNameAttribute` and `PSDReportSettingsModuleImageAttribute` have constructors that accept a `string s` parameter, but this parameter is completely ignored in the logic. It is unclear why this parameter exists.
*   **Mixed Container Usage:** The `RegisterTypes` method receives an `IContainerRegistry` (Prism abstraction) but the actual registration logic inside `Initialize()` uses the injected `IUnityContainer` (Unity specific). This bypasses the Prism abstraction layer, which could cause issues if the container implementation details differ or if the container wrapper is expected to manage lifestyle scopes.
*   **Property Getter Side Effects:** In `PSDReportSettingsModuleImageAttribute`, the `AssemblyImage` property getter performs a method call `AssemblyInfo.GetImage(...)` and assigns it to the private field `_img` every time the getter is accessed. This is not a pure getter; it causes a new image lookup (and potentially a new object allocation) on every read access, rather than returning a cached value.
*   **Empty OnInitialized:** The `OnInitialized` method is empty. If the module requires runtime initialization logic (like starting services or registering region views), it is not present here. The module currently only performs type registration.
