How exactly does the datatype checking of Vector work? The documentation states that an exception occurs at runtime if there was a wrong argument pushed to the Vector. However if I try this:
Code:
private var numberVector:Vector.<Number> = new Vector.<Number>();
...
numberVector.push(thumbnailInstance)
And then I trace it, I get NaN (cos it is a thumbnail ). However, no exception is being thrown.
Is it possible to read the datatype of a vector?[code]...

public static const db:String = "http://dbpedia.org/resource/";
public static const rdf:String = "http://www.w3.org/1999/02/22-rdf-syntax-ns#";

Checking Cache as Bitmap doesn't work, you have to .cacheAsBitmap = true with actionscript?

View 5 Replieswhat I try I can't get the Setter function to work on a vector.<object>
Mean while the getter works fine Example as below
Code:
public function get frameData() :Vector.<Object>
{
trace("getter");[code]....
the code runs fine without the set function, but not without the get.
I'm getting
ActionScript Code:
1067: Implicit coercion of a value of type
__AS3__.vec:Vector.ie.aro.floorplanviewer.model.buildingVOs:ConfigurationVO>[code]....
which surprises me as ConfigurationVO inherits from NodeVO.Is the compiler really not able to figure out that a Vector of a superclass should be able to hold a reference to a Vector of a subclass?

I am currently being confused by the Vector class.I wrote a beautiful XML to TypedClass parser. Works beautifully and without fault. UNTIL a co-worker noticed we got a Conversion Error for Vector.<Number> to Vector.<*>.
Every Vector I've ever tested all extend Vector.<*>.
Vector.<Sprite>, Vector.<String>, Vector.<Point>, Vector.<Boolean>, Vector.<TextField>, Vector.<CustomObject>, etc etc etc. ALL of them.
<type name="__AS3__.vec::Vector.<String>" base="__AS3__.vec::Vector.<*>" isDynamic="true" isFinal="false" isStatic="false">
<extendsClass type="__AS3__.vec::Vector.<*>"/>
[code]...
But then when I use describeType on Vector.<Number>, Vector.<uint> and Vector.<int>.
<type name="__AS3__.vec::Vector.<Number>" base="Object" isDynamic="true" isFinal="true" isStatic="false">
<extendsClass type="Object"/>
<constructor>
[code]....
Now I have accounted for these 3 vectors individually as even uint and int does not extend Vector.<Number> as I would have expected.
And my parsing function works for all types correctly again. But my confusion comes as to WHY this is the case, and why I couldn't find any documentation on the subject.
so as my title says. I'm wondering if specifying the datatype in actionscript 3 on variables actually makes code run faster

Has anyone implemented a Set class in ActionScript? Specifically, a Set which is similar to Python's set implementation (unordered, unique, O(1) membership, etc). I'd like to be able to iterate over it using for each, perform operations like union and intersection and get a list of all the contained items... Which would all be possible to implement using Dictionary and Proxy, but I'd rather not reimplement it if someone's already done the heavy lifting.

View 3 RepliesThrough an XMLSocket, I get a basic datatype as a String value, such as "int", "String", "Array", etc... I would like to instantiate a new variable of the specified datatype. Something along the lines of the following psuedocode:
Code:
function createVariable(type:String, value:*):void
{
var dataTypeRef:* = getDataTypeRef( type ); [code]......
The title of this post may not make much sense, let me explain. I have a function:
findSurface(origin:Point, vector:Point, attempts:Number):Point The function has an obscure use, but the idea is thus: given those three arguments, returns a point IF the 'line' (created by the origin and vector arguments) intersects the object the function is called on. [but that is another story...]
More importantly, if there is no point of intersection at all, what should the function return? Void? Null? Undefined? Object? Or can I use one of those return types instead of Point incase the function does not encounter an intersection?
is there a way to convert dynamicly?
that's the default way to convert a String:
var toVal:* = int("5");
var toVal:* = Boolean("true");
but I wan't to do this:
var type:String = "int";
var toVal:* = type("5"); // <<<<< how can I do this
is there a method to return the datatype of a variable?
