# ManageUsers
|
|||
|
|
|
|||
|
|
## 1. Purpose
|
|||
|
|
This module defines the view and view model interfaces for the *Manage Users* feature within the application’s UI layer. It serves as a contract between the presentation layer (view) and the business logic/data-binding layer (view model) in a pattern consistent with MVVM (Model-View-ViewModel), enabling separation of concerns and testability. The interfaces themselves are intentionally minimal—extending base interfaces (`IBaseView` and `IBaseViewModel`)—suggesting that core functionality (e.g., lifecycle management, navigation, data context) is abstracted at the base level, while *Manage Users* adds no additional surface area beyond this base contract.
|
|||
|
|
|
|||
|
|
## 2. Public Interface
|
|||
|
|
No public members are declared directly in either interface. Both interfaces are empty markers that inherit from base interfaces:
|
|||
|
|
|
|||
|
|
- **`IManageUsersView`**
|
|||
|
|
- *Signature*: `public interface IManageUsersView : IBaseView`
|
|||
|
|
- *Behavior*: Serves as the contract for the UI view (e.g., XAML page or control) responsible for rendering the user management UI. It inherits all contract obligations of `IBaseView` (e.g., `DataContext` assignment, initialization hooks, disposal patterns), though the specifics of `IBaseView` are not included here.
|
|||
|
|
|
|||
|
|
- **`IManageUsersViewModel`**
|
|||
|
|
- *Signature*: `public interface IManageUsersViewModel : IBaseViewModel`
|
|||
|
|
- *Behavior*: Serves as the contract for the view model backing `IManageUsersView`. It inherits all contract obligations of `IBaseViewModel` (e.g., property change notification, command registration, state management), though the specifics of `IBaseViewModel` are not included here.
|
|||
|
|
|
|||
|
|
> **Note**: Actual functionality (e.g., user list loading, user creation/deletion commands, selection handling) is not exposed in these interfaces and must be defined in concrete implementations or in the base interfaces (`IBaseView`, `IBaseViewModel`).
|
|||
|
|
|
|||
|
|
## 3. Invariants
|
|||
|
|
- `IManageUsersView` must be implemented by a class that satisfies the contract of `IBaseView`.
|
|||
|
|
- `IManageUsersViewModel` must be implemented by a class that satisfies the contract of `IBaseViewModel`.
|
|||
|
|
- The view and view model must be paired such that the view’s `DataContext` is an instance of `IManageUsersViewModel` (or its concrete implementation), per standard MVVM binding conventions.
|
|||
|
|
- No additional runtime invariants (e.g., thread affinity, initialization order) are specified in the source.
|
|||
|
|
|
|||
|
|
## 4. Dependencies
|
|||
|
|
- **Depends on**:
|
|||
|
|
- `DTS.Common.Base.IBaseView`
|
|||
|
|
- `DTS.Common.Base.IBaseViewModel`
|
|||
|
|
- `DTS.Common.Base` namespace (likely contains base types and contracts for UI components)
|
|||
|
|
|
|||
|
|
- **Depended on by**:
|
|||
|
|
- Concrete implementations of `IManageUsersView` (e.g., a XAML view class)
|
|||
|
|
- Concrete implementations of `IManageUsersViewModel` (e.g., a view model class)
|
|||
|
|
- DI containers or navigation services that resolve or inject these interfaces
|
|||
|
|
- Other modules that reference `IManageUsersView`/`IManageUsersViewModel` for composition or testing (e.g., unit tests, integration layers)
|
|||
|
|
|
|||
|
|
## 5. Gotchas
|
|||
|
|
- **Empty interfaces**: The interfaces contain no members beyond inheritance, which may indicate incomplete refactoring, future extensibility, or reliance on convention over explicit contract definition. Developers should verify that `IBaseView` and `IBaseViewModel` provide sufficient functionality for the *Manage Users* feature.
|
|||
|
|
- **Ambiguity in feature scope**: Without additional members, it is unclear whether user-specific operations (e.g., `LoadUsersAsync()`, `DeleteUserCommand`) are expected to be defined in the base interfaces or in derived classes. This could lead to inconsistent implementations.
|
|||
|
|
- **No versioning or deprecation markers**: The absence of attributes (e.g., `[Obsolete]`) or versioning hints makes it difficult to assess whether these interfaces are stable or in flux.
|
|||
|
|
- **None identified from source alone.**
