+# Commands
+
+## Documentation: `DTS.Common.Classes.Viewer.Commands.RelayCommand`
+
+### 1. Purpose
+This module provides an implementation of the `System.Windows.Input.ICommand` interface designed to delegate logic to methods passed as parameters. It exists to support the MVVM (Model-View-ViewModel) pattern within the DTS Viewer application, allowing UI controls (like buttons) to bind to actions defined in ViewModels without requiring the creation of separate concrete command classes for every action.
+
+### 2. Public Interface
+
+**Constructors**
+
+*   `public RelayCommand(Action<object> execute)`
+    *   Initializes a new instance of the `RelayCommand` class that can always execute.
+    *   **Parameter:** `execute` — The execution logic delegate.
+    *   **Behavior:** Calls the overloaded constructor with `null` for the `canExecute` predicate.
+
+*   `public RelayCommand(Action<object> execute, Predicate<object> canExecute)`
+    *   Initializes a new instance of the `RelayCommand` class.
+    *   **Parameters:**
+        *   `execute` — The execution logic delegate.
+        *   `canExecute` — The execution status logic delegate (optional).
+    *   **Behavior:** Throws an `ArgumentNullException` named "execute" if the `execute` delegate is null. Assigns delegates to internal readonly fields.
+
+**Methods**
+
+*   `public bool CanExecute(object parameter)`
+    *   Determines if the command can execute in its current state.
+    *   **Behavior:** Returns `true` if `_canExecute` is `null`. Otherwise, returns the result of invoking `_canExecute(parameter)`
