# DIChannels
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
This module defines foundational interfaces for the digital input channels view-model/view layer within the TTS (presumably *Test Terminal System*) test setup import functionality. It establishes the contract between the UI presentation layer (`IDigitalInputChannelsView`) and its corresponding data-binding context (`IDigitalInputChannelsViewModel`), enabling separation of concerns and testability in the UI architecture. The interfaces are minimal and serve as extension points in a larger MVVM (Model-View-ViewModel) pattern implementation, specifically for digital input channel configuration or monitoring UI components.
|
||
|
|
|
||
|
|
## 2. Public Interface
|
||
|
|
- **`IDigitalInputChannelsView`**
|
||
|
|
*Signature:* `public interface IDigitalInputChannelsView : IBaseView`
|
||
|
|
*Behavior:* Represents the view layer for digital input channels. It inherits from `IBaseView`, implying it participates in a standard view lifecycle (e.g., initialization, binding, disposal). No additional members are defined in this interface; it acts as a marker interface for type-safe view resolution and dependency injection.
|
||
|
|
|
||
|
|
- **`IDigitalInputChannelsViewModel`**
|
||
|
|
*Signature:* `public interface IDigitalInputChannelsViewModel : IBaseViewModel`
|
||
|
|
*Behavior:* Represents the view-model layer for digital input channels. It inherits from `IBaseViewModel`, implying standard view-model responsibilities (e.g., command handling, state management, INotifyPropertyChanged implementation). It exposes a single property:
|
||
|
|
- `View`: A get/set property of type `IDigitalInputChannelsView`, used to establish the view-model-to-view link (typical in MVVM for view-first or view-model-first activation patterns).
|
||
|
|
|
||
|
|
## 3. Invariants
|
||
|
|
- `IDigitalInputChannelsView` must implement `IBaseView`.
|
||
|
|
- `IDigitalInputChannelsViewModel` must implement `IBaseViewModel`.
|
||
|
|
- The `View` property on `IDigitalInputChannelsViewModel` must be assignable (read-write), allowing the view-model to hold a reference to its associated view instance.
|
||
|
|
- No additional runtime guarantees (e.g., thread-safety, initialization order) are specified in the source; these are assumed to be handled by the consuming framework or implementation.
|
||
|
|
|
||
|
|
## 4. Dependencies
|
||
|
|
- **Depends on:**
|
||
|
|
- `DTS.Common.Base` namespace (specifically `IBaseView` and `IBaseViewModel`).
|
||
|
|
- **Depended on by (inferred):**
|
||
|
|
- Likely consumed by a DI container or UI framework to resolve/view-attach logic for digital input channel UI modules.
|
||
|
|
- Implied consumers include concrete implementations of `IDigitalInputChannelsView` (e.g., WPF `UserControl`, WinForms `Panel`) and `IDigitalInputChannelsViewModel` (e.g., a class managing DI channel state).
|
||
|
|
- No direct usage in the provided source; dependencies are inferred from the MVVM pattern and namespace structure.
|
||
|
|
|
||
|
|
## 5. Gotchas
|
||
|
|
- **No behavior defined:** Both interfaces are empty beyond inheritance and the `View` property. Actual functionality (e.g., channel data, commands, events) must be implemented in concrete classes or extended interfaces—this module only provides structural scaffolding.
|
||
|
|
- **Ambiguous `View` lifecycle:** The source does not clarify ownership or lifecycle management of the `View` reference (e.g., is it weak/strong? who sets/disposes it?). This is common in MVVM but can lead to memory leaks if not handled carefully.
|
||
|
|
- **No versioning or extensibility hooks:** The interfaces are sealed by design (no methods/events), limiting future extension without breaking changes.
|
||
|
|
- **None identified from source alone.**
