Description
The `GetEnumerator` method of the `SelectionSystem` class provides an enumerator that iterates through the collection of selected objects. This method is sealed, meaning it cannot be overridden in derived classes, and it is virtual, allowing it to be invoked on instances of the `SelectionSystem` class. The method returns an `IEnumerator` of type `System.Object`, enabling iteration over the selected items in a non-generic manner.
Usage
To use the `GetEnumerator` method, simply call it on an instance of the `SelectionSystem` class. This will return an enumerator that can be used to iterate over the selected objects. This is particularly useful when you need to perform operations on each selected item or when you need to access the items in a sequential manner.
Ensure that you handle the enumerator properly, typically using a `foreach` loop in C# to automatically manage the enumerator's lifecycle.
Example
SelectionSystem selectionSystem = new SelectionSystem();
// Add some objects to the selection system
selectionSystem.Add(new GameObject("Object1"));
selectionSystem.Add(new GameObject("Object2"));
// Use GetEnumerator to iterate over the selected objects
IEnumerator<object> enumerator = selectionSystem.GetEnumerator();
while (enumerator.MoveNext())
{
object selectedObject = enumerator.Current;
// Perform operations with selectedObject
// For example, print the object's name
GameObject gameObject = selectedObject as GameObject;
if (gameObject != null)
{
// Access properties or methods of the GameObject
string name = gameObject.Name;
// Do something with the name
}
}
