Documentation: Download Data Interfaces

1. Purpose

This module defines the contractual interfaces for the View and ViewModel components within a "Download Data" feature, adhering to a Model-View-ViewModel (MVVM) architectural pattern. It establishes a type hierarchy for download-specific UI components by extending base view and viewModel interfaces, allowing for polymorphic handling of download views within the broader DTS.Common system.

2. Public Interface

IDownloadDataView

• Namespace: DTS.Common.Interface
• Inheritance: IBaseView
• Signature:

  public interface IDownloadDataView : IBaseView
  

• Description: A marker interface intended to represent the View layer for a data download operation. It inherits from IBaseView but defines no additional members.

IDownloadDataViewModel

• Namespace: DTS.Common
• Inheritance: IBaseViewModel
• Signature:

  public interface IDownloadDataViewModel : IBaseViewModel
  

• Description: A marker interface intended to represent the ViewModel layer for a data download operation. It inherits from IBaseViewModel but defines no additional members.

3. Invariants

• Base Type Compliance: Any class implementing IDownloadDataView must also implement IBaseView. Similarly, any class implementing IDownloadDataViewModel must also implement IBaseViewModel.
• Member Expectations: As both interfaces currently define no members, they rely entirely on the contracts defined by their parent interfaces (IBaseView and IBaseViewModel).

4. Dependencies

• External Dependencies:
  • DTS.Common.Base: Both interfaces depend on this namespace for IBaseView and IBaseViewModel.
• Dependents: Unknown from source alone. It is expected that concrete View and ViewModel classes within the "Download Data" feature will implement these interfaces.

5. Gotchas

• Empty Interfaces: Both IDownloadDataView and IDownloadDataViewModel are currently empty (marker interfaces). They do not define properties such as DownloadCommand, ProgressPercentage, or Cancel methods that one might expect for a download feature. Functionality must be inferred from the base interfaces or implemented in concrete classes without interface enforcement.
• Namespace Inconsistency: The View interface (IDownloadDataView) resides in DTS.Common.Interface, while the ViewModel interface (IDownloadDataViewModel) resides in the root DTS.Common namespace. This discrepancy may cause confusion regarding file organization or referencing.
