C# :: Datatype To Replace The Dictionary Datatype?
Feb 9, 2012
i'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 am not sure what to datatype my currentSWF var. What is that? function onCompleteHandler(loadEvent:Event) { var currentSWF = loadEvent.currentTarget.content; swfHolderMC.addChild(currentSWF); }
basically 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.

Through 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?
I am trying to run an if statement based on the a variables datatype
var theArray:Array = ['element1','element2'}]; var theString:String = "I am string"; trace(gettype(theArray)); // In php gettype() is what I use to get the type. Is there a similar function in as3?
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.
I have been following the samples code of Foundation ActionScript 3.0.
I have imported a jpeg into Flash CS3 IDE Library and Exported(Linkage) it to be used in action script by giving a class name 'Image'. And when I am trying to compile the file its showing error: 1136: Incorrect number of arguments. Expected 2. and 1067: Implicit coercion of a value of type Image to an unrelated type flash.display:Bitmap.
How to attach the jpeg to the stage as a Bitmap datatype using as3..
The dictionary use strict equals(===) for key comparison, how to change the comparison, so I can use my standard for comparison, for example, I have a class named Student:
class Student{ var id:int; var name:String;[code]....
I want Dictionary use id to compare if the two keys are equal, not use strict equal(===) to compare if the key is the same.
I'm having some real trouble getting .replace to actually replace something. Here's my code...
[Code]...
I can trace both newFiles[i] and keywords[i][whatever], but the replace doesn't replace anything. The regex is valid as well. I'm using regexr to test it, and it works perfectly there... but will not for me and I don't know why.
Normally in Flex you use a collection like ArrayCollection as the dataprovider for components. I often have data stored as a dictionary whose values I would like to use as a dataprovider.
I'm working with a large set of hierarchical taxonomic terms, where each term ("203") has a matching "term203" movie clip on the stage, and am having trouble getting a recursive function to return all of a given term's descendants.There is a main Dictionary() object with the following nested organization for each term:
...where the [object Movie Clip]'s instance name would be "term203". All of these object:subObjectArray items ("terms") are stored in a master taxonomy:Dictionary() object.I've been trying to make a recursive function (which is in itself already a little above my head) that takes the click.target of a movie clip and returns a new Dictionary() object with all of the children and grandchildren and great grandchildren (etc) of that term, in the same, nested organization described above.
The code below traces the right number of recursive loops, but the returned Dictionary() object only contains the first run's terms (only the immediate children of the requested term).
var taxonomy:Dictionary = new Dictionary(); // ...Term info is loaded into taxonomy from a JSON-style text file) // ...MOUSE_OVER event listeners are added to each
[code]....
I certainly do not claim to be the most efficient AS3 programmer, so I am open to alternative configurations. However, after trying static and nested Arrays, I would prefer to continue using the Dictionary() object as my main pool.As noted, only the immediate children end up animating in the revealChildren() function. It's mystifying to me then, that in the getAllChildren() function, all of the descendants trace sequentially (well in no particular order) in the output window.Also I can't get any sort of name or property out of the subSet Object. That could be the problem.I've only tested it as far as 'two generations,' but it seems that only the first round of calling the function successfully adds those terms to the new Dictionary() object and returns it intact to the animating function.
I'm often seeing others using a Dictionary object in their AS3 code that simply maps objects by String keys and wondering if there is any advantage at all of using a Dictionary over a simple Object if String keys are used. Anyone know any details on this? I would suppose that since an Object is more lightweight it should be faster and preferable over a Dictionary if used with String keys.
why the Dictionary class ignores setPropertyIsEnumerable? I found this bug at bugs.adobe, seems the prototype might be involved in some devious way.Here is some test code:
var obj:Object = { 'a': 0, 'b': 1,[code]......
Notice that the Dictionary is still enumerating the property "a" even though it was told not to.
What is the correct way to determine if a Dictionary contains a particular key or not?
In Java I can do: HashMap x= new HashMap(); x.containsKey("test"); // returns true/false Is this the correct way in AS3? var xictionary = new Dictionary(); x["test"] == null
