# Model

### 1. **Purpose**  
`MenuCommand` is a concrete implementation of `ICommand` used to wrap menu item selections in the Hamburger Menu module. It serves as a lightweight command handler that, when executed, notifies a registered callback (`MenuItemPressedDelegate`) with the menu item’s unique identifier (`Id`). Its purpose is to decouple UI menu interactions from business logic by translating WPF command execution into a domain-specific callback, enabling loose coupling between the menu UI and the rest of the system.

---

### 2. **Public Interface**  

- **`MenuCommand(string id, MenuItemPressedDelegate menuItemPressed)`**  
  Constructor. Initializes the command with a unique `id` (string) and a delegate (`MenuItemPressedDelegate`) to invoke on execution.  
  - *Parameters*:  
    - `id`: A non-null string identifying the menu item.  
    - `menuItemPressed`: A delegate of type `MenuItemPressedDelegate` (defined in `DTS.Common.Interface.Menu.HamburgerMenu`) to be invoked with `id` when the command executes.  

- **`bool CanExecute(object parameter)`**  
  Always returns `true`. Implements `ICommand.CanExecute`. The command is always executable regardless of the `parameter` value.  

- **`void Execute(object parameter)`**  
  Invokes the `MenuItemPressed` delegate with the stored `Id`. Implements `ICommand.Execute`. The `parameter` is ignored.  

- **`event EventHandler CanExecuteChanged`**  
  Implements `ICommand.CanExecuteChanged`. Declared but *never raised* — consumers should not rely on this event for change notifications.

---

### 3. **Invariants**  
- `Id` is immutable after construction (declared `readonly`).  
- `MenuItemPressed` delegate is non-null at construction (no null-check is performed; passing `null` will cause a `NullReferenceException` on `Execute`).  
- `CanExecute` always returns `true`; no runtime conditions affect executability.  
- `CanExecuteChanged` is declared but *never raised* — no external changes to `CanExecute` status are ever signaled.  
- `Execute` ignores its `parameter` argument entirely.

---

### 4. **Dependencies**  
- **Imports/References**:  
  - `DTS.Common.Interface.Menu.HamburgerMenu` — Provides the `MenuItemPressedDelegate` type (not defined in this file; assumed to be a delegate type in the referenced namespace).  
  - `System` and `System.Windows.Input` — For `EventHandler`, `ICommand`, and WPF command infrastructure.  
- **Consumers**:  
  - Presumably instantiated by UI layer code (e.g., in a view model or menu builder) that maps menu items to `MenuCommand` instances.  
  - Depends on external code to supply the `MenuItemPressedDelegate` implementation (not visible in this file).  

---

### 5. **Gotchas**  
- **`CanExecuteChanged` is never raised** — This violates typical `ICommand` conventions (e.g., WPF command bindings may not update UI state if they rely on this event). If command executability *should* change dynamically, this implementation is incomplete.  
- **No null-safety**: Passing `null` for `menuItemPressed` in the constructor will cause a `NullReferenceException` at `Execute` time.  
- **`parameter` is unused** — `Execute` ignores its argument, which may cause issues if consumers expect parameter-based logic (e.g., passing context via `parameter`).  
- **No validation of `id`** — No checks for `null` or empty `id`; while not explicitly causing failure, this may lead to ambiguous menu item identification downstream.  
- **No thread-safety guarantees** — `CanExecuteChanged` event and delegate invocation are not synchronized.  

None identified beyond the above.
