CheckTrigger

1. Purpose

This module defines the core interfaces for the Check Trigger feature within the DTS (likely Data Tracking System) architecture. It establishes the contract between the view and view model layers for components responsible for triggering and managing check operations—likely periodic or event-driven validation/sync tasks—within a MVVM (Model-View-ViewModel) pattern. The interfaces ICheckTriggerView and ICheckTriggerViewModel serve as base abstractions that concrete implementations must fulfill, enabling decoupled UI and business logic for check-triggering functionality.

2. Public Interface

No public functions, methods, or properties are defined directly in these interfaces. Both interfaces are marker interfaces inheriting from base interfaces in the DTS.Common.Base namespace:

• ICheckTriggerView

  • Signature: public interface ICheckTriggerView : IBaseView
  • Behavior: Represents the view layer contract for a check-trigger UI component. It inherits from IBaseView, implying it adheres to a common view contract (e.g., lifecycle, binding context, or UI state management), but no additional API surface is exposed here.

• ICheckTriggerViewModel

  • Signature: public interface ICheckTriggerViewModel : IBaseViewModel
  • Behavior: Represents the view model layer contract for managing check-trigger state and logic. It inherits from IBaseViewModel, implying standard view model capabilities (e.g., property change notification, command handling), but no additional API surface is exposed here.

Note

: All meaningful behavior (e.g., commands, properties like IsTriggerEnabled, LastCheckTime) must be defined in concrete implementations or in IBaseView/IBaseViewModel. This file only declares the type roles.

3. Invariants

• ICheckTriggerView must be implemented by a UI component (e.g., XAML view, control, or page) that participates in the check-trigger workflow.
• ICheckTriggerViewModel must be implemented by a view model that coordinates check-trigger logic and binds to an ICheckTriggerView.
• The pair (ICheckTriggerView, ICheckTriggerViewModel) must be used in a standard MVVM binding relationship (e.g., view sets its BindingContext to an instance of ICheckTriggerViewModel).
• Both interfaces are marker interfaces—they carry no behavioral contract beyond their type identity and base inheritance.

4. Dependencies

• Depends on:
  • DTS.Common.Base (specifically IBaseView and IBaseViewModel).
• Depended on by:
  • Concrete view classes (e.g., CheckTriggerPage : Page, ICheckTriggerView) and view model classes (e.g., CheckTriggerViewModel : ICheckTriggerViewModel) in the UI layer.
  • Dependency injection or composition containers likely register types against these interfaces.
  • Other modules (e.g., DTS.Common.Core.CheckTrigger) likely consume these interfaces to bind or wire up check-trigger components.

5. Gotchas

• No behavior defined here: Developers may mistakenly expect methods/properties in these interfaces; all logic resides in implementations or base interfaces.
• Ambiguity in IBaseView/IBaseViewModel: Behavior of ICheckTriggerView and ICheckTriggerViewModel is entirely contingent on the contracts of IBaseView and IBaseViewModel, which are not provided here. Their semantics (e.g., required lifecycle methods, binding patterns) must be consulted separately.
• No versioning or extensibility signals: The interfaces are empty—adding future functionality may require breaking changes or new derived interfaces (e.g., ICheckTriggerView2).
• Namespace reuse: Both interfaces reside in DTS.Common.Interface, but no other types in this namespace are shown; ensure no naming conflicts exist with other *Trigger interfaces (e.g., IScheduleTriggerView).

None identified beyond the above.
