# CheckTrigger
|
|||
|
|
|
|||
|
|
## 1. Purpose
|
|||
|
|
This module defines the view and view model interfaces for a *Check Trigger* feature within the DTS (likely *Data Tracking System* or similar domain) architecture. It serves as a contract layer in a MVVM (Model-View-ViewModel) pattern, enabling decoupled UI implementation for components that present or manage trigger-checking logic—such as validating whether certain conditions or events have been met. The interfaces inherit from base abstractions (`IBaseView`, `IBaseViewModel`), indicating adherence to a standardized UI layer hierarchy.
|
|||
|
|
|
|||
|
|
## 2. Public Interface
|
|||
|
|
No public *implementations* are provided in the source, only interface declarations. The interfaces themselves are:
|
|||
|
|
|
|||
|
|
- **`ICheckTriggerView`**
|
|||
|
|
```csharp
|
|||
|
|
public interface ICheckTriggerView : IBaseView
|
|||
|
|
```
|
|||
|
|
Represents the view layer for the Check Trigger feature. As it inherits `IBaseView`, it is expected to support standard view behaviors (e.g., lifecycle management, data binding context) defined in the base interface—though the exact members of `IBaseView` are not included here and must be referenced separately.
|
|||
|
|
|
|||
|
|
- **`ICheckTriggerViewModel`**
|
|||
|
|
```csharp
|
|||
|
|
public interface ICheckTriggerViewModel : IBaseViewModel
|
|||
|
|
```
|
|||
|
|
Represents the view model layer for the Check Trigger feature. As it inherits `IBaseViewModel`, it is expected to expose properties and commands for UI binding and state management—again, with specifics defined in `IBaseViewModel`, which is external to this source.
|
|||
|
|
|
|||
|
|
## 3. Invariants
|
|||
|
|
- `ICheckTriggerView` and `ICheckTriggerViewModel` are *pure interface declarations* with no method, property, or event members defined in this file.
|
|||
|
|
- Both interfaces are part of the `DTS.Common.Interface` namespace and inherit from their respective base interfaces (`IBaseView`, `IBaseViewModel`), implying that all implementations must satisfy the contracts of those base interfaces.
|
|||
|
|
- No additional validation rules, ordering guarantees, or state constraints are specified in the provided source.
|
|||
|
|
|
|||
|
|
## 4. Dependencies
|
|||
|
|
- **Internal dependencies**:
|
|||
|
|
- `DTS.Common.Base` — provides `IBaseView` and `IBaseViewModel`.
|
|||
|
|
- **No external dependencies** (e.g., no third-party libraries or other DTS modules) are imported in the provided files.
|
|||
|
|
- **Consumers**: Likely used by UI modules (e.g., WPF, MAUI, or other XAML-based clients) that implement the `ICheckTriggerView` and bind to `ICheckTriggerViewModel` instances. The actual usage would be in higher-level modules (not included here).
|
|||
|
|
|
|||
|
|
## 5. Gotchas
|
|||
|
|
- **Ambiguity in base interfaces**: The behavior and contract of `ICheckTriggerView` and `ICheckTriggerViewModel` are entirely dependent on the definitions of `IBaseView` and `IBaseViewModel`, which are not included. Without those, the interfaces are effectively empty placeholders.
|
|||
|
|
- **No feature-specific API surface**: Despite the module name *CheckTrigger*, the interfaces contain *no* methods or properties related to checking triggers (e.g., no `CheckAsync()`, `TriggerStatus`, etc.). This suggests either:
|
|||
|
|
- The feature logic resides entirely in the view model’s implementation (not declared in the interface),
|
|||
|
|
- Or this is a placeholder for future expansion,
|
|||
|
|
- Or the actual trigger-checking logic is handled elsewhere (e.g., in a service or domain model).
|
|||
|
|
- **No documentation comments**: Neither interface includes XML documentation, making intent and usage unclear beyond naming.
|
|||
|
|
- **None identified from source alone.**
