# CheckChannels
|
|||

|

|
|
## Documentation: CheckChannels Module Interfaces
|
|||
|
|
|
|||
|
|
### 1. Purpose
|
|||
|
|
This module defines the interface contracts for the *CheckChannels* feature within the DTS UI framework. It establishes a clean separation of concerns between view and view model layers for both the main CheckChannels UI and its associated ribbon menu component. The interfaces `ICheckChannelsView`, `ICheckChannelsViewModel`, `ICheckChannelsMenuView`, and `ICheckChannelsMenuViewModel` collectively enable dependency inversion and testability for the feature’s UI components, allowing concrete implementations to be injected and swapped without tight coupling.
|
|||
|
|
|
|||
|
|
### 2. Public Interface
|
|||
|
|
All interfaces are *marker interfaces*—they inherit from base interfaces but declare no additional members.
|
|||
|
|
|
|||
|
|
- **`ICheckChannelsView : IBaseView`**
|
|||
|
|
Marker interface for the view component of the CheckChannels feature. Indicates that a class serves as the UI layer (e.g., a WPF `UserControl` or `Window`) for the core CheckChannels functionality.
|
|||
|
|
|
|||
|
|
- **`ICheckChannelsViewModel : IBaseViewModel`**
|
|||
|
|
Marker interface for the view model of the CheckChannels feature. Indicates that a class encapsulates the UI state and behavior for the core CheckChannels functionality.
|
|||
|
|
|
|||
|
|
- **`ICheckChannelsMenuView : IRibbonView`**
|
|||
|
|
Marker interface for the ribbon menu view associated with the CheckChannels feature. Indicates that a class provides the UI for ribbon-based menu items (e.g., buttons, dropdowns) related to CheckChannels.
|
|||
|
|
|
|||
|
|
- **`ICheckChannelsMenuViewModel : IRibbonViewModel`**
|
|||
|
|
Marker interface for the ribbon menu view model. Indicates that a class manages the state and logic for ribbon menu items in the CheckChannels context.
|
|||
|
|
|
|||
|
|
> **Note**: No methods, properties, or events are declared in any of these interfaces. Behavior and data contracts are inherited from `IBaseView`, `IBaseViewModel`, `IRibbonView`, and `IRibbonViewModel`.
|
|||
|
|
|
|||
|
|
### 3. Invariants
|
|||
|
|
- All four interfaces are *pure marker interfaces* with no additional contract beyond their base interface inheritance.
|
|||
|
|
- Implementations of `ICheckChannelsView` and `ICheckChannelsMenuView` must be compatible with their respective base view interfaces (`IBaseView`, `IRibbonView`)—e.g., supporting view lifecycle, data binding, or ribbon-specific behaviors as defined by those bases.
|
|||
|
|
- Implementations of `ICheckChannelsViewModel` and `ICheckChannelsMenuViewModel` must conform to the semantics of `IBaseViewModel` and `IRibbonViewModel`, respectively (e.g., property change notification, command exposure).
|
|||
|
|
- No ordering, initialization, or dependency guarantees are specified *within this module*—these are determined by the base interfaces and consumer code.
|
|||
|
|
|
|||
|
|
### 4. Dependencies
|
|||
|
|
- **Depends on**:
|
|||
|
|
- `DTS.Common.Base` (for `IBaseView`, `IBaseViewModel`)
|
|||
|
|
- `DTS.Common.RibbonControl` (for `IRibbonView`, `IRibbonViewModel`)
|
|||
|
|
- **Used by**:
|
|||
|
|
- UI framework code that resolves or injects view/view model implementations via these interfaces (e.g., DI containers, view-first navigation logic).
|
|||
|
|
- Concrete implementations of the CheckChannels feature (e.g., `CheckChannelsView : ICheckChannelsView`) and its ribbon menu counterpart.
|
|||
|
|
- **No direct dependencies on other DTS modules** beyond the base and ribbon control layers.
|
|||
|
|
|
|||
|
|
### 5. Gotchas
|
|||
|
|
- **No behavior defined here**: These interfaces convey *no operational semantics*—developers must inspect `IBaseView`, `IBaseViewModel`, `IRibbonView`, and `IRibbonViewModel` to understand expected behavior (e.g., property change patterns, command wiring).
|
|||
|
|
- **Risk of over-abstraction**: The use of marker interfaces may obscure intent; ensure naming (`CheckChannels` vs. `CheckChannelsMenu`) is consistently applied across implementations to avoid confusion.
|
|||
|
|
- **Ribbon-specific semantics**: `ICheckChannelsMenuView` inherits from `IRibbonView`, implying integration with a ribbon UI framework (e.g., DevExpress, Fluent.Ribbon). Consumers must ensure ribbon-specific requirements (e.g., `RibbonControl` initialization order) are respected.
|
|||
|
|
- **No versioning or extensibility signals**: Changes to the underlying base interfaces (`IBaseView`, `IRibbonViewModel`, etc.) may silently affect implementations—tight coupling to base contracts is implicit.
