What is the most efficient way to empty an Array or Vector in ActionScript 3?I've always just re-initialized them:
vector = new Vector.<T>();
array = [];
It doesn't look like there's an empty() function or anything similar.
I would like to subclass an Array or Vector to dispatch and Event.CHANGE when any elements value changes.
View 2 RepliesI have a list of 99 item (something like a phone book) and I will like to sort them in different method. Part of the 99 item might be empty, so the requirement is to move the empty field behind the sorted data in every sorting behavior, here the code we have so far:

I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array();
var slideShowDataArray:Array = new Array();
slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.
I want to arrange certain objects from a vector/array into a gird
Currently, I know how to do this during the creation of the objects.
Here's the grid function I've created:
function ArrangeInGrid(uiRow:uint, uiCol:uint, iOffsetX:int, iOffsetY:int):void
{
for(var i:uint = 0; i < uiRow; ++i)
{
[Code].....
Now I want to be able to apply the same logic of arranging objects in an array/vector in to a grid, how do I do it?
Or suggest a more efficient way to do so (if you have).
Notes:
I want it to be flexible in how many rows and columns the grid can have. The vector I'm using already has the cards in it. I can't just push the cards into the vector cuz of the way I manually created my cards.

Ow eh im using Flash MX2k4 v7.2
I would like to take advantage of all the goodness of the newer Vector class for FP10, but it seems it is marked as final. I am doing some intensive mathematical processing in Actionscript, and repeatedly process arrays of Numbers. I have previously been using my own subclass of Array(I call it NumericArray), with added functions such as sum(), mean(), add(), multiply(), etc. This works very well and allows for some clean OO code. However, I am finding through profiling that about 95% of my processing time occurs in the functions of these objects. I need more performance out of these arrays.
I want to use a Vector, as it provides some performance enhancements. I want to specifically use a Vector.<Number>. Unfortunately, I cannot subclass Vector as it is marked final. What is the best and cleanest way to imitate what I was previously doing with a subclass of Array, to a Vector.<Number>?
I have thought about passing around Vector.<Number> variables instead of my custom class and just using utility functions to manipulate, but this is not good OO design and will be a pain to use, not to mention ugly.

View 2 RepliesSo I have this waky idea that I would put an array list (or list) or items inside a vector.
For example an array of fruit containing bananas, apples and oranges inside a vector of type fruit.
I could get the array list and thenwalk through it to get what I want.
I've run into a strange Vector out of range error when trying to splice a Vector array. The idea is to cut off the Vector array after a certain point....

vec.push(1);vec.push(2);vec.push(3);vec.push(4);vec.push(5);
vec.splice(3,vec.length); // output RangeError: Error #1125: The index 5 is out of range 5.
The strange thing is that it works perfectly, if I change the Vector to a regular array like:

I have a quick question for you all. I'm trying to convert over some ActionScript code to C++ and am having a difficult time with this one line:
private var edges:Vector.<Array> What is this exactly? Is this essentially a multidimensional vector then? Or is this simply declaring the vector as a container? I understand from researching that vectors, like C++ vectors, have to be declared with a type. However, in C++ I can't just put down Array, I have to use another vector (probably) so it looks like:
I don't expect you guys to know the C++ equivalent because I'm primarily posting this with AS tags, but if you could confirm my understand of the AS half, that would be great. I did some googling but didn't find any cases where someone used Array as it's type.

I've been working on this for a while, and thought I understood the BitmapData class at least well enough to do basic stuff with it, but I'm doing something wrong.
I'm trying to make a preload function that will load external JPEGs, store them in an Array as BitmapData objects, then distribute them to thumbnail objects after all the images are loaded. The thumbnails are based on an external class I wrote, which already has a function to accept variable data.
My problem is, I can't seem to find a way to store BitmapData objects in an Array. I've even tried using a Vector.<BitmapData> object, but I get the same result, which is no data stored.
Here's the function, isolated from the rest of the script.
[Code]....
The result of this function is supposed to be, a series of images loaded one after the other, stacked 5 pixels down from each other. However, the actual result is, only the last loaded image is displayed. That's true for any number I place in the 'for' loop, only the last loaded image gets displayed.
Obviously I'm doing something wrong with the loading of the 'bitBucket' BitmapData, because it seems to be writing over the previous BitmapData in the Vector series.

I'm developing a small library and trying to outweigh the pros and cons of using Vector vs. Array. So far, I can only think of a few things to think of: Vector only works for FP10, while Array works for both 9 and 10. Vector is typed (which is a wonderful, fabulous thing), but if I'm only using the Array as a private variable, so I have full control over what goes in and comes out of it, this factor may not play as great a part anymore, but definitely great protection.
I believe I heard somewhere that Vector is a lot faster than Array, yet in a quick inconclusive speed test I did a while back, it didn't seem to make any real difference at all. Is Vector really faster than Array? If so, is it faster in all aspects, or only faster in certain situations just as uint is only faster than Number when using byteshifting?
