# 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`**
|
|
```csharp
|
|
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`**
|
|
```csharp
|
|
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.** |
