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

  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

  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.
