Description
The `GetEnumerator` method of the `Editor.HistoryStack` class provides an enumerator that iterates through the history stack. This method is sealed, meaning it cannot be overridden in derived classes, and it is virtual, allowing for potential extension in the base class. The method returns an enumerator of type `System.Collections.Generic.IEnumerator`, which allows for iteration over the collection of items stored in the history stack.
Usage
To use the `GetEnumerator` method, you can call it directly on an instance of `HistoryStack`. This is typically done implicitly when using a `foreach` loop in C#. The enumerator returned by this method provides the ability to iterate over the elements in the history stack in a forward-only manner.
Example
// Example of using GetEnumerator with a foreach loop
// Assume HistoryStack<int> is a stack of integers
Editor.HistoryStack<int> historyStack = new Editor.HistoryStack<int>();
// Add some items to the history stack
historyStack.Add(1);
historyStack.Add(2);
historyStack.Add(3);
// Iterate over the history stack using GetEnumerator implicitly
foreach (int item in historyStack)
{
// Process each item
// e.g., Console.WriteLine(item);
}
