# Documentation: DTS.Common.Events.Groups.GroupList

## 1. Purpose

This module defines event types for the Group List feature using Prism's event aggregation pattern. These events enable decoupled publish/subscribe communication between components in the application when group-related user actions occur, such as selecting groups or initiating an edit operation. The events carry integer-based identifiers as payloads.

---

## 2. Public Interface

### `GroupListEditGroupEvent`
- **Signature:** `public class GroupListEditGroupEvent : PubSubEvent<int>`
- **Behavior:** An event that publishes an `int` payload, intended to signal that a group edit operation should be initiated. The payload represents a single group identifier.

### `GroupListGroupSelectedEvent`
- **Signature:** `public class GroupListGroupSelectedEvent : PubSubEvent<int[]>`
- **Behavior:** An event that publishes an `int[]` payload, intended to signal that one or more groups have been selected. The payload is an array of group identifiers.

---

## 3. Invariants

- `GroupListEditGroupEvent` always carries a single `int` payload representing a group ID.
- `GroupListGroupSelectedEvent` always carries an `int[]` payload representing zero or more group IDs.
- Both event types inherit from `PubSubEvent<T>`, guaranteeing they follow Prism's event aggregation contract.

---

## 4. Dependencies

**This module depends on:**
- `Prism.Events` — Provides the `PubSubEvent<T>` base class for event aggregation.

**What depends on this module:**
- Unknown from source alone. Consumers would be any component that publishes or subscribes to these events via Prism's `IEventAggregator`.

## 5. Gotchas

- **Stale XML documentation:** Both classes contain XML comments referencing `GroupTemplateListGroupTemplateSelectedEvent` and "called when a template is selected." This appears to be copy-paste documentation that does not match the actual class names or their intended purposes (group editing and group selection, not template selection). The documentation should not be trusted as accurate.
