ManageUsers

1. Purpose

This module defines the core view and view-model interfaces for the Manage Users feature within the DTS (likely Data Tracking System) application architecture. It serves as a contract layer in a MVVM (Model-View-ViewModel) pattern, ensuring loose coupling between UI presentation (IManageUsersView) and business/logic state management (IManageUsersViewModel). The interfaces themselves are intentionally minimal—extending base abstractions (IBaseView, IBaseViewModel)—indicating that this feature follows a standardized structural convention used across the codebase for user management functionality.

2. Public Interface

No public methods, properties, or events are declared directly in either interface. Both interfaces are marker interfaces with no additional members beyond those inherited from their base types.

• IManageUsersView : IBaseView
  Represents the UI layer contract for the Manage Users view. As it inherits IBaseView, it is expected to support standard view lifecycle or binding behaviors defined in IBaseView (e.g., data context assignment, initialization hooks), though those specifics are not visible in this file.

• IManageUsersViewModel : IBaseViewModel
  Represents the view-model contract for Manage Users logic. As it inherits IBaseViewModel, it is expected to expose standard view-model capabilities (e.g., command binding, state management, property change notifications) as defined in IBaseViewModel.

Note

: Actual functionality (e.g., user list retrieval, user creation/deletion commands, filtering logic) is not present in these interfaces and must be defined elsewhere (e.g., in concrete implementations or derived interfaces).

3. Invariants

• IManageUsersView and IManageUsersViewModel must be used together as a view/view-model pair per MVVM conventions.
• Both interfaces are part of the DTS.Common.Interface namespace, implying they are intended for cross-module consumption (e.g., shared between UI and service layers).
• Inheritance from IBaseView/IBaseViewModel implies adherence to the base contract’s semantics (e.g., lifecycle, binding context), though the exact invariants depend on those base interfaces (not shown here).
• No additional validation rules, state constraints, or ordering guarantees are specified in this source.

4. Dependencies

• Depends on:
  • DTS.Common.Base namespace (specifically IBaseView and IBaseViewModel).
• Depended on by:
  • Concrete implementations of IManageUsersView (e.g., a WPF UserControl or Window class).
  • Concrete implementations of IManageUsersViewModel (e.g., a ManageUsersViewModel class).
  • DI containers or navigation frameworks that resolve or bind these interfaces to concrete types.
  • Other modules that reference this interface for dependency inversion (e.g., a module registering or managing user management features).

5. Gotchas

• Minimal contract: These interfaces contain no members, so developers may mistakenly assume they carry functionality. All behavior must be implemented in derived classes or via extension (e.g., via IBaseView/IBaseViewModel or additional interfaces).
• Ambiguity in base interfaces: Behavior and invariants of IBaseView and IBaseViewModel are not documented here; their definitions are required to understand full semantics.
• No feature-specific extensibility: If future enhancements require adding properties (e.g., Users, SelectedUser) or commands (e.g., RefreshCommand), this interface must be modified—breaking existing implementations. Consider using partial interfaces or composition if extensibility is anticipated.
• None identified from source alone.
