Editing Lazy initialization (section)

===ActionScript 3===
The following is an example of a class with lazy initialization implemented in [[ActionScript]]:
<syntaxhighlight lang="actionscript">
package examples.lazyinstantiation
{
	public class Fruit 
	{
		private var _typeName:String;
		private static var instancesByTypeName:Dictionary = new Dictionary();
	 
		public function Fruit(typeName:String):void
		{
			this._typeName = typeName;
		}
		
		public function get typeName():String 
		{
			return _typeName;
		}
	 
		public static function getFruitByTypeName(typeName:String):Fruit
		{
			return instancesByTypeName[typeName] ||= new Fruit(typeName);
		}
	 
		public static function printCurrentTypes():void
		{
			for each (var fruit:Fruit in instancesByTypeName) 
			{
				// iterates through each value
				trace(fruit.typeName);
			}
		}
	}
}
</syntaxhighlight>
Basic use:
<syntaxhighlight lang="actionscript">
package
{
	import examples.lazyinstantiation;
	
	public class Main 
	{
		public function Main():void
		{
			Fruit.getFruitByTypeName("Banana");
			Fruit.printCurrentTypes();
	 
			Fruit.getFruitByTypeName("Apple");
			Fruit.printCurrentTypes();
	 
			Fruit.getFruitByTypeName("Banana");
			Fruit.printCurrentTypes();
		}
	}
}
</syntaxhighlight>
