# Pagination

### Purpose
This module defines interfaces for pagination and filtering functionality within the DTS system. It provides marker interfaces for pagination views and view models, as well as a contract for filterable list views. These interfaces enable a consistent pattern for implementing paginated, searchable UI components across the application.

### Public Interface

**IPaginationView** (extends `IBaseView`)
- Marker interface with no members. Identifies views that support pagination.

**IPaginationViewModel** (extends `IBaseViewModel`)
- Marker interface with no members. Identifies view models that support pagination.

**IFilterableListView**
- `void Filter(object tag, string term)` - Applies a filter to the list view using the provided tag and search term.
- `void ClearAllFilters()` - Removes all active filters from the list view.
- `string ListViewId { get; }` - Returns the identifier for this list view instance.

### Invariants
- `IFilterableListView.ListViewId` must return a consistent identifier for the lifetime of the view instance.
- Both `IPaginationView` and `IPaginationViewModel` must be compatible with their respective base types (`IBaseView` and `IBaseViewModel`) from `DTS.Common.Base`.

### Dependencies
- **Depends on**: `DTS.Common.Base` (for `IBaseView` and `IBaseViewModel`)
- **Depended on by**: Unknown from source alone (likely pagination UI components and list views)

### Gotchas
- `IPaginationView` and `IPaginationViewModel` are marker interfaces with no members, suggesting they may be used for type checking or dependency injection registration rather than defining behavioral contracts.
- The `Filter` method accepts `object tag` as a parameter; the expected type and usage of this tag is not specified in the interface.
