Actionscript 3 :: Read Datatype Of A Vector?
May 24, 2010Is it possible to read the datatype of a vector?[code]...

View 1 RepliesHow 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.
I have to convert one string type field to date datatype in flex.
View 3 Repliesi'm working on converting an Action Sript class to C# and now i'm choosing a proper data types to replace ActionScript data Types ... and i wondered what is the best C# datatype to replace the Dictionary Datatype in Actionscript here's a sample code for example
public static const db:String = "http://dbpedia.org/resource/";
public static const rdf:String = "http://www.w3.org/1999/02/22-rdf-syntax-ns#";
public static const skos:String = "http://www.w3.org/2004/02/skos/core#";

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

View 5 Repliesbasically what I am trying to do is dynamically add graphics using actionscript. So far it has worked but I ran into a problem. I am using addChild to add the pictures and the instance name.addChild(imageLoader). I need to convert the xml parsed data (xmlData.player[0].@position) to a instance name which I believe is data type MovieClip. So I am trying to convert my xml which is a string to a movieclip. Here are snippets of code:
var position:MovieClip = XmlData.player[0].@position; //Doesn't workgives Error #1034: Type Coercion failed: cannot convert XMLList@1f2d2e09 to flash.display.MovieClip.
var position:String = XmlData.player[0].@position; //Does work

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?

I have a large vector drawing (imagine 5000x5000) that i want to break up into separate pieces. I know that I can convert this vector drawing into a bitmap and then use the copyPixels method to create many separate bitmaps of the different regions of the original vector drawing, but is there any way to subdivide it into movieclips that just contain vector graphics instead of a bitmap?The reason im dividing a big chunk of vector graphics into smaller pieces is for performance reasons, so flash would only render a small part of this big chunk at a time (only certain regions/voxels/subdivisions are rendered at a time). But bitmaps apparently take up a lot of memory and the system im using would take much less memory if these subdivisions could be preserved in their original vector graphics form.
I imagine I could use masks somehow to achieve this effect (for each subdivision, duplicate the huge image and mask only the region that the subdivision represents), but I dont know the performance costs of masking or if this will create other problems.So is there anyway to split up a movieclip of vector graphics into smaller movieclips of vector graphics the same way copyPixels can with bitmaps?
A friend of mine has a Flash Action script running on a LAMP server that currently reads an xml config file. He's asked me if it's possible to remove the xml file, and replace it somehow with a system (lets call it an 'auto xml generator') that intercepts the request to read that file and generates an output, so it appears to all intents and purposes as if the file still exists and contains the contents that has actually been returned from our auto xml generator'
