# 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 specific View, ViewModel, and Model implementations with the Unity dependency injection container. Additionally, it defines assembly-level attributes to expose metadata (name, image, group, and region) to the main application shell, enabling the module to be discovered and displayed as an available component.

## 2. Public Interface

### Class: `PSDReportSettingsModule`
Implements `Prism.Modularity.IModule`.

*   **Constructor**: `PSDReportSettingsModule(IUnityContainer unityContainer)`
    *   Accepts an `IUnityContainer` instance via constructor injection and stores it in a readonly field.
*   **Method**: `void Initialize()`
    *   Registers three type mappings in the Unity container:
        *   `IPSDReportSettingsViewModel` mapped to `PSDReportSettingsViewModel`.
        *   `IPSDReportSettingsModel` mapped to `PSDReportSettingsModel`.
        *   `IPSDReportSettingsView` mapped to `PSDReportSettingsView`.
*   **Method**: `void RegisterTypes(IContainerRegistry containerRegistry)`
    *   Implements `IModule.RegisterTypes`. It invokes the `Initialize()` method.
*   **Method**: `void OnInitialized(IContainerProvider containerProvider)`
    *   Implements `IModule.OnInitialized`. This method is currently empty.

### Class: `PSDReportSettingsModuleNameAttribute`
Inherits from `TextAttribute`.

*   **Constructor**: `PSDReportSettingsModuleNameAttribute()` / `PSDReportSettingsModuleNameAttribute(string s)`
    *   Hardcodes the `AssemblyName` property to `AssemblyNames.PSDReportSettings.ToString()`. The string argument `s` in the overloaded constructor is ignored.
*   **Property**: `string AssemblyName { get; }`
    *   Returns the hardcoded assembly name string.
*   **Method**: `Type GetAttributeType()`
    *   Returns `typeof(TextAttribute)`.
*   **Method**: `string GetAssemblyName()`
    *   Returns the value of the `AssemblyName` property.

### Class: `PSDReportSettingsModuleImageAttribute`
Inherits from `ImageAttribute`.

*   **Constructor**: `PSDReportSettingsModuleImageAttribute()` / `PSDReportSettingsModuleImageAttribute(string s)`
    *   Initializes a private `BitmapImage` field (`_img`) by calling `AssemblyInfo.GetImage`. The string argument `s` is ignored.
*   **Property**: `BitmapImage AssemblyImage { get; }`
    *   Gets the image by calling `AssemblyInfo.GetImage` with the `AssemblyNames.PSDReportSettings` enum value.
*   **Property**: `string AssemblyName { get; }`
    *   Returns `AssemblyNames.PSDReportSettings.ToString()`.
*   **Property**: `string AssemblyGroup { get; }`
    *   Returns `eAssemblyGroups.Viewer.ToString()`.
*   **Property**: `eAssemblyRegion AssemblyRegion { get; }`
    *   Returns `eAssemblyRegion.PSDReportSettingsRegion`.
*   **Methods**:
    *   `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 Prism module is identified by the string `"PSDReportSettings"` via the `[Module]` attribute.
*   **Assembly Attributes**: The assembly is decorated with both `PSDReportSettingsModuleNameAttribute` and `PSDReportSettingsModuleImageAttribute` with `AllowMultiple = false`.
*   **Registration Mapping**: The `Initialize` method guarantees that `IPSDReportSettingsViewModel`, `IPSDReportSettingsModel`, and `IPSDReportSettingsView` are registered with the container upon module initialization.
*   **Region Assignment**: This module is statically bound to the region `eAssemblyRegion.PSDReportSettingsRegion`.

## 4. Dependencies

### Internal Dependencies
*   **DTS.Common**: Referenced for `AssemblyNames`, `AssemblyInfo`, `eAssemblyGroups`, and `eAssemblyRegion`.
*   **DTS.Common.Interface**: Referenced for base classes `TextAttribute` and `ImageAttribute`.
*   **Local Types**: The module depends on the existence of `PSDReportSettingsViewModel`, `PSDReportSettingsModel`, and `PSDReportSettingsView` (and their corresponding interfaces), though these types are not defined in the provided source snippet.

### External Dependencies
*   **Prism.Ioc**: For `IContainerProvider` and `IContainerRegistry`.
*   **Prism.Modularity**: For `IModule` and `ModuleAttribute`.
*   **Unity**: For `IUnityContainer` (used for specific registration logic).
*   **System.Windows.Media.Imaging**: For `BitmapImage`.

### Consumers
*   The DTS Viewer main application shell (inferred from the module structure and `eAssemblyGroups.Viewer` group assignment).

## 5. Gotchas
*   **Mixed Container Abstractions**: The module implements `IModule`, which provides a `RegisterTypes(IContainerRegistry containerRegistry)` method intended for container-agnostic registration. However, the implementation ignores the `containerRegistry` argument and instead uses the injected `IUnityContainer` instance via the `Initialize()` method. This ties the module specifically to Unity, bypassing Prism's container abstraction layer.
*   **Redundant Constructor Arguments**: Both attribute classes possess constructors accepting a `string s` argument. This argument is unused in both constructors, suggesting legacy code or a requirement of the base attribute constructor signature that was implemented but not utilized.
*   **Property Side Effects**: In `PSDReportSettingsModuleImageAttribute`, the getter for `AssemblyImage` re-executes `AssemblyInfo.GetImage(...)` and reassigns the private field `_img` every time it is accessed, rather than returning the cached value.
*   **Empty OnInitialized**: The `OnInitialized` method is explicitly empty. If the View needs to be loaded into a region automatically upon startup, that logic is absent from this module class.
