Documentation: IUISettingsView and IUISettingsViewModel Interfaces

1. Purpose

This module defines two marker interfaces—IUISettingsView and IUISettingsViewModel—that establish the View and ViewModel contracts for a UI Settings feature within an MVVM (Model-View-ViewModel) architecture. These interfaces exist to provide type identity for UI Settings components, allowing them to be identified, resolved, or constrained independently of their base types. They serve as extension points for future UI-specific settings functionality while maintaining compatibility with the broader IBaseView and IBaseViewModel hierarchies.

2. Public Interface

IUISettingsView

• Namespace: DTS.Common.Interface
• Signature: public interface IUISettingsView : IBaseView
• Description: A marker interface for UI Settings views. Inherits from IBaseView but defines no additional members. Intended to be implemented by view components responsible for displaying or editing UI settings.

IUISettingsViewModel

• Namespace: DTS.Common.Interface
• Signature: public interface IUISettingsViewModel : IBaseViewModel
• Description: A marker interface for UI Settings view models. Inherits from IBaseViewModel but defines no additional members. Intended to be implemented by view model components that manage the state and behavior for UI settings views.

---

3. Invariants

• Inheritance constraint: IUISettingsView must always inherit from IBaseView, and IUISettingsViewModel must always inherit from IBaseViewModel.
• Member contract: Neither interface defines any members of its own; all behavior contracts are inherited from their respective base interfaces.
• Type identity: Any class implementing IUISettingsView or IUISettingsViewModel is implicitly also a IBaseView or IBaseViewModel respectively.

Note: Additional invariants (e.g., threading requirements, lifecycle guarantees) cannot be determined from the source alone and would be defined in IBaseView and IBaseViewModel.

---

4. Dependencies

This module depends on:

• DTS.Common.Base — Provides IBaseView and IBaseViewModel base interfaces.

What depends on this module:

• Cannot be determined from source alone. Consumers would include concrete view and view model implementations for UI settings, as well as any dependency injection containers, navigation services, or factory classes that resolve or create UI Settings components by these interface types.

---

5. Gotchas

• Empty marker interfaces: Both interfaces define no members. This is a valid pattern for type discrimination, but developers should be aware that all actual behavior contracts come from IBaseView and IBaseViewModel. If UI Settings-specific members are needed in the future, these interfaces would need to be extended.
• Base interface contracts unknown: The actual responsibilities, properties, and methods that implementers must provide are defined in IBaseView and IBaseViewModel, which are not included in the provided source. Developers should consult those definitions to understand the full contract
