I'm trying to do something along the following:
Code:
//Loop through all items in the dictionary to update each and every one
for (var key:DisplayObjectContainer in containerDict)
[code].....
for (var k in dictionary)
{
var key:KeyType = KeyType(k);
var value:ValType = ValType(dictionary[k]); // <-- lookup
// do stuff
}
This is what I use to loop through the entries in a dictionary. As you can see in every iteration I perform a lookup in the dictionary. Is there a more efficient way of iterating the dictionary (while keeping access to the key)?
I am working on a native extension for Flash. I am going to invoke my native methods from Flash and pass Dictionary objects where those objects have various data members of various data types. These property types are dynamic and might not be known at compile time.So I found that we have a method called FREGetObjectProperty that says it can return the value given the property name. But in this case since we dont know the property name since it is dynamic, how to extract the property names and values from the Dictionary objects?

I am encountering a problem in my app only when it is run in flash player 10.1.85.3. Some earlier player versions I have tried are working fine.From what I can tell it seems related to the following:

When searching for objects (not strings) in Dictionary objects using the 'in' operator, if the object is not found in the Dictionary object, it will be searched for in the delegate objects. With 10.1, the toString operator will be called on the Object if not found in the Dictionary. This can cause problems with Proxy objects who need to define the callProperty function or it will generate a RTE. ...what it means "it will be searched for in the delegate objects"?

I created multiple classes for a platforming game in AS3 and when i am making the levels i simply drag the objects of a certain class to the stage from the library. My problem is that i am unable loop through all of the objects of class type wall from another class of players.(so that i can make every player created not go through every wall created)
Like: for(i=0 i<numberofwalls i++){
do sumthing with wallobject(i)
}
Are there any functions that can return the number of walls dragged to the screen and one that lets me access each individual wall dragged to the screen?

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:

I have had a long post somewhere on here and just wanted to start a specific post on just associative arrays. First of all I have an array which I don't know if it's an array or an associative array or an object or both. ie: I read that the below would be an object but works as an array too.
The problem is when I use this array as references to instantiate classes in a runtime shared library.I seem to be able to create the appropriate arrays and objects BUT I definately can't use/acess them properly. I massive confusion between movieclips and objects. I get a forced conversion error when I try to add objects to a movieclip . simply because I want to add the mc elements to the stage.

The issue I am running across is this: I encoded and embedded a movie clip to act as the background. There are other animations that can and will loop, as the movie resets itself. But there are some elements that I only want to run once and not repeat once the embedded movie loops (link introductions, where objects fly in and transition into the button). How can I set the one time animations to fire just once, while keeping the embedded animation on a loop?

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.
View 2 RepliesI'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:
{ [object Movie Clip] : { "tid":203, "parent":99, "name":"Culture", selected:false, "otherData":"etc" } }
...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.
View 1 Replieswhy 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

in Java this: dict.keySet()

Right now I am using ArrayCollection. But I want to change that to Set as I want make sure do duplicate values come.
var addressList:ArrayCollection = new ArrayCollection();
One way is I can use Dictionary and store addresses as a key. And I can just use keys to iterate. But I am looking for Java HashSet like implementation.
I am writing my destructor but I am not sure how to make sure that my Dictionary object is completely dismantled.
Do I just walk the keys and 'delete' the objects? If so do I need to destroy the keys? or are they already removed when the object is removed from the Dictionary?[code]...
I have an ARRAY which contains single symbols and DICTIONARY in where every symbol in array is attached to unique string, what I want to do - is to merge ARRAY and DICTIONARY together, and as a result receive RESULT_ARRAY where order of elements is equal to ARRAY but elements are replaced according to a DICTIONARY.
Code:
//for example
//this is what we have -
var originalA:Array = new Array ();
originalA[0]="y";
