ActionScript 3.0 :: Dictionary - How To Enumerate
Dec 19, 2010The great thing about dictionary: one can use objects as keys. The bad thing: compiler still believes that the keys are strings.

ActionScript 3.0 :: Enumerate Shared Objects Created By An Application?
Dec 20, 2010Is there any way to enumerate the shared objects created by an application? I'd like to create a number of individual shared objects and then enumerate them when the application starts again so it knows what's been stored. I want to store them individually because there could be a large number of them and I only need to use a few in any one application session and I don't want to read them all as one big shared object
I know I could put their names in a "master" shared object, enumerate that list of names, and manage it that way, but being able to enumerate the shared objects directly seems much cleaner.

View 2 RepliesActionscript 3 :: Building A New Dictionary Out Of An Old One?
Aug 31, 2010I'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.
Actionscript 3 :: Different Between Object And Dictionary?
Mar 1, 2011I'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.

Aug 29, 2011In my parsley container, I'm instantiating an object 'A' that contains a Dictionary (flash.utils.Dictionary).
I would like to create this Dictionary using parsley and inject it to 'A'.
This dictionary pairs structure is: key=id of object 'B', value='B'
