ActionScript 3.0 :: Aggravating Sparse Array For/next Order Vs. Need For .length?

May 21, 2009

it would seem (and I guess I read Senocular's thing on this ages ago, but never really believed it)...

Code:
var a:Array = [];
a[0] = "a";
a[1] = "b";[code].....

But make it sparse and it all goes to hell... i.e. if a[0] isn't defined, cases where you're using it as a piece of useful information, there's no guarantee they'll spit out in the same order.On the other hand, if you make it an object, you can't get its length.Does anyone know an elegant way to poll an Array for the number of occupied addresses, and allow it to for/each or for/as in the right order? In PHP it's as easy as count() and foreach(... as $k=>$v). While the latter doesn't do much good for associative arrays, it always works in order on numerical arrays, whether sparse or not...

Actionscript 3 :: Remove Equally Spaced Elements From An Array With Length Of 'n' To Match A Given Length 'y'?

Mar 9, 2011

Let's say I have array foo and a positive integer y, where foo.length > y.I want to remove elements from foo so that foo.length becomes y (or very close to it).Also, I need to preserve the first and last element of foo. The indices of the removed elements must be spaced apart as equally as possible. Foo can be sliced, or it can be used to create a new array.

Example: if foo = [a,b,c,d,e,f,g,1,2,3,4,5] and y = 6, then trimmedfoo could be [a,c,e,g,2,4,5] or maybe [a,c,e,2,4,5], but not [a,c,e,g,2,4] because the last element of foo is missing.

ActionScript 3.0 :: Remove Values Past An Array Length And Clear Entire Array?

Oct 8, 2009

I'm using the .unshift method therefore the newest values go into [0] and the rest are pushed down.

What is a good method to remove a value from an array once it has passed a certain length? For example i only want my array to hold 5 values.

Also, is there a method for clearing the entire array, ie removing all values? Or will i have to manually change all the values with a loop?

Flex :: Efficiently Fill Data Gaps In An Sparse ArrayCollection?

Aug 10, 2010

I have an ArrayCollection of Objects. Each Object with three attributes:CustomerID, Income and DateMy goal is to chart this data for each customer (or a couple together) in a Income by Date LineChart display. Selection of customers is done with ArrayCollection filters.Data is fetched from an SQL database, however, each customer has some data points missing.f there was zero income on August 8, 2010 there will be no entry for that.Charting the ArrayCollection as is, is misleading because there is no indication of the missing data points.One way to solve this is to artificially add zero points for the missing dates for each customer. However, this would explode the data set (and impact performance).

this problem is blowing my mind i have a for loop that i want to go through my entire array but it seems to not be counting the last element in the arraay!

for(var i:int=0; i<gridControl.game.blockG.length; i++){
trace(i +" "+gridControl.game.blockG.length);
}

and the last line of code it spits out is "83 84" meaning that there are 84 items in the array but it only ran through to 83...i dont understand why its doing this.

ActionScript 3.0 :: Sort Array By Length Of Element?

Mar 20, 2009

I have an array which contains strings. I need to sort the array by the length of the string - longest string first.

e.g. if

myArray[0] = "xxx";
myArray[1] = "x";
myArray[2] = "xxxxxxx";

[Code].....

but it didn't work. I guess length is not a property of each array element.

By the way, the array is already large (270,000 elements) - so I need the sort to work very fast, and I don't want to be adding anything else into the array.
