Package	flash.utils
Class	public dynamic class Dictionary
Inheritance	Dictionary Object

Language version:

ActionScript 3.0

Runtime version:

The Dictionary class lets you create a dynamic collection of properties, which uses strict equality (===) for key comparison. When an object is used as a key, the object's identity is used to look up the object, and not the value returned from calling toString() on it.

The following statements show the relationship between a Dictionary object and a key object:

 var dict = new Dictionary();

 var obj = new Object();

 var key:Object = new Object();

 key.toString = function() { return "key" }

 
 dict[key] = "Letters";

 obj["key"] = "Letters";

 
 dict[key] == "Letters"; // true

 obj["key"] == "Letters"; // true

 obj[key] == "Letters"; // true because key == "key" is true b/c key.toString == "key"

 dict["key"] == "Letters"; // false because "key" === key is false

 delete dict[key]; //removes the key
