Josh Tynjala commented on FLEX-36:
----------------------------------
I decided to do some further testing of Vector.<*>. I tried some similar code
with a variety of data types, as shown below, and only the numeric types
failed. That may not change anything, but it's worth noting, I think.
var doVector:Vector.<DisplayObject> = new <DisplayObject>[new Sprite(), new
Shape(), new MovieClip()];
trace("display objects:", doVector, doVector as Vector.<*>);
//display objects: [object Sprite],[object Shape],[object MovieClip] [object
Sprite],[object Shape],[object MovieClip]
var objectVector:Vector.<Object> = new <Object>[{}, {}, {}];
trace("objects:", objectVector, objectVector as Vector.<*>);
//objects: [object Object],[object Object],[object Object] [object
Object],[object Object],[object Object]
var boolVector:Vector.<Boolean> = new <Boolean>[true, true, false];
trace("booleans:", boolVector, boolVector as Vector.<*>);
//booleans: true,true,false true,true,false
var stringVector:Vector.<String> = new <String>["One", "Two", "Three"];
trace("strings:", stringVector, stringVector as Vector.<*>);
//strings: One,Two,Three One,Two,Three
var numberVector:Vector.<Number> = new <Number>[1, 2, 3];
trace("numbers:", numberVector, numberVector as Vector.<*>);
//numbers: 1,2,3 null
var intVector:Vector.<int> = new <int>[-1, 0, 1];
trace("ints", intVector, intVector as Vector.<*>);
//ints -1,0,1 null
var uintVector:Vector.<uint> = new <uint>[1, 2, 3];
trace("uints", uintVector, uintVector as Vector.<*>);
//uints 1,2,3 null
var xmlVector:Vector.<XML> = new <XML>[<one>one</one>, <two>two</two>,
<three>three</three>];
trace("xml", xmlVector, xmlVector as Vector.<*>);
//xml one,two,three one,two,three

> Key: FLEX-36
> URL: https://issues.apache.org/jira/browse/FLEX-36
> Project: Apache Flex
> Issue Type: Improvement
> Reporter: Josh Tynjala
> Assignee: Bertrand Delacretaz
> Priority: Minor
> Labels: List, collections
>
> VectorList and VectorCollection, similar to ArrayList and ArrayCollection.
> Feels weird that I need to convert Vectors to Arrays to use in Flex
> collections.
> In case anyone is unaware, you can cast Vector.<WhateverTypeYouWant> as
> Vector.<*>. Works with the "as" and "is" keywords, as you can see below:
> var strings:Vector.<String> = new <String>["One", "Two", "Three"];
> trace(strings is Vector.<*>); //true
> var generic:Vector.<*> = strings as Vector.<*>;
> trace(strings) //One, Two, Three
