# Legend

### Purpose
This module defines the view and ViewModel interfaces for a Legend component within the DTS Viewer. The ViewModel interface provides access to its associated view, suggesting a composition pattern where the ViewModel owns a reference to its View.

### Public Interface

**`ILegendView`** (interface)
- Inherits from: `IBaseView`
- No members defined. Serves as a marker interface for Legend views.

**`ILegendViewModel`** (interface)
- Inherits from: `IBaseViewModel`
- Members:
  - `ILegendView View { get; }` — Gets the Tab View associated with this ViewModel.

### Invariants
- `ILegendViewModel.View` must return a valid `ILegendView` implementation.
- The XML comment indicates this view is specifically a "Tab View", suggesting the Legend is rendered as a tabbed interface element.

### Dependencies
- **Depends on**: `DTS.Common.Base` (for `IBaseView` and `IBaseViewModel`)
- **Depended on by**: Unknown from source alone (likely concrete Legend implementations and Viewer composition)

### Gotchas
- The XML documentation refers to "Tab View" which may indicate specific UI placement expectations not evident from the interface alone.
