CustomerDetails

1. Purpose

This module defines the foundational view and view model interfaces for the customer details feature within the DTS system. It establishes a contract between the UI layer (via ICustomerDetailsView) and the presentation logic layer (via ICustomerDetailsViewModel), adhering to a standard MVVM (Model-View-ViewModel) architectural pattern. These interfaces extend base abstractions (IBaseView, IBaseViewModel) to provide a consistent, extensible structure for customer-related UI components, enabling separation of concerns and testability.

2. Public Interface

No public implementations are provided in the source, only interface declarations. The interfaces themselves are:

• ICustomerDetailsView

  public interface ICustomerDetailsView : IBaseView
  

  Represents the view layer for customer details. It inherits from IBaseView, implying it supports standard view behaviors (e.g., data binding context, lifecycle events, or UI state management), though the specifics of IBaseView are not included here.

• ICustomerDetailsViewModel

  public interface ICustomerDetailsViewModel : IBaseViewModel
  

  Represents the view model layer for customer details. It inherits from IBaseViewModel, implying it exposes properties and commands for UI binding (e.g., customer data, save/cancel commands), but the actual members are not defined in this file.

3. Invariants

• Both interfaces are marker interfaces—they carry no additional members beyond their base interface, so no behavioral invariants are enforced here.
• They must be implemented by concrete types that satisfy the contracts of IBaseView and IBaseViewModel, respectively.
• The namespace DTS.Common.Interface suggests these are part of a shared contract layer, implying consumers must adhere to the约定 that ICustomerDetailsView and ICustomerDetailsViewModel are paired (e.g., a view binds to a corresponding view model).

4. Dependencies

• Depends on:
  • DTS.Common.Base (specifically IBaseView and IBaseViewModel, though their definitions are external to this file).
• Depended on by:
  • Unknown from this source alone. Likely consumed by UI framework code (e.g., WPF, MAUI, or a custom MVVM framework) and concrete implementations in higher-level modules (e.g., DTS.UI.CustomerDetails).
  • No direct usage of these interfaces is visible in the provided snippets.

5. Gotchas

• Ambiguity in base interfaces: Since IBaseView and IBaseViewModel are referenced but not defined here, the actual capabilities (e.g., required properties/methods) of ICustomerDetailsView and ICustomerDetailsViewModel are not determinable from this source.
• No explicit contract: These interfaces are empty beyond inheritance, so they provide no compile-time guarantees about the shape of customer details UI logic—implementation details (e.g., property names, command signatures) must be inferred from concrete classes or other documentation.
• Potential for misuse: Without additional constraints or documentation, developers might pair mismatched view/view model types, relying only on runtime binding or naming conventions.
• None identified from source alone.
