PowerAndBattery

1. Purpose

This module defines the foundational interfaces for the Power and Battery settings view layer within the system settings UI. Specifically, IPowerAndBatteryView and IPowerAndBatteryViewModel serve as contract interfaces that establish the separation of concerns between the view (UI layer) and view model (business/logic layer) for the Power and Battery configuration section. They inherit from IBaseView and IBaseViewModel respectively, indicating adherence to a common MVVM (Model-View-ViewModel) architectural pattern used across the application. The interfaces themselves contain no additional members, suggesting this section currently has no specialized view/view model behavior beyond the base contract.

2. Public Interface

No public methods, properties, or events are defined directly on these interfaces. They are marker interfaces extending base contracts:

• IPowerAndBatteryView
  Signature: public interface IPowerAndBatteryView : IBaseView
  Behavior: Represents the view contract for the Power and Battery settings section. As a marker interface inheriting IBaseView, it signals to the framework or DI container that this type corresponds to the view component for this settings area. No additional behavior is specified in this source.

• IPowerAndBatteryViewModel
  Signature: public interface IPowerAndBatteryViewModel : IBaseViewModel
  Behavior: Represents the view model contract for the Power and Battery settings section. As a marker interface inheriting IBaseViewModel, it signals to the framework or DI container that this type corresponds to the view model component for this settings area. No additional behavior is specified in this source.

3. Invariants

• Both interfaces must be implemented by types that fulfill the contracts of their respective base interfaces (IBaseView and IBaseViewModel).
• Since no members are declared, the interfaces impose no additional runtime constraints beyond those inherited from IBaseView/IBaseViewModel.
• The interfaces are intended to be used as marker interfaces—their presence (or absence) in a type’s inheritance hierarchy signals its role in the Power and Battery settings section.

4. Dependencies

• Dependencies of this module:
  • DTS.Common.Base namespace (specifically IBaseView and IBaseViewModel, though their definitions are not provided here).
• Dependencies on this module:
  • Any concrete view or view model implementation for the Power and Battery settings section must implement IPowerAndBatteryView and IPowerAndBatteryViewModel respectively.
  • Framework or DI infrastructure likely uses these interfaces to resolve or wire up the Power and Battery settings UI components (e.g., via view model first navigation or view-first activation patterns).
  • Other modules (e.g., settings navigation, settings registry) may reference these interfaces to register or locate the Power and Battery section.

5. Gotchas

• Ambiguity of purpose: The interfaces are empty and provide no guidance on expected behavior, data binding properties, or lifecycle events. Consumers must rely on documentation or inspection of concrete implementations (not provided here) to understand how this section is implemented.
• Potential for future extension: Since no members are defined, future additions to these interfaces (e.g., methods for refreshing battery status or handling power plan changes) would be breaking changes for existing implementations.
• No indication of state or data model: The interfaces do not expose any properties (e.g., BatteryPercentage, IsCharging)—these would be defined in concrete classes or in IBaseViewModel/IBaseView.
• None identified from source alone.
