Great article. I did not know AS3 Arrays were implemented internally in this way. This will definitely influence my design decisions when architecting Flex apps.

Hey, great stuff, really interesting.

But.. Im getting a very very very annoying runtime error from your code highlight thingy everytime I drag my mouse over them.

Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.

Regards, Arwid.

[...] leave a comment » Did you ever worked in AS3 with Byte Array and AMF data serialization for transferring object over network ? It really simplify everything. Of course there is a size overhead. But the bottom line is that we can save hundreds of hours by using it. Since Flash 10, there is one big flaw with AMF: it doesn’t support Vector. Well it’s not true, The FlasPlayer support it, but not what link to it. So you still can serialize Vector object in a byte array and save it in a file for example, but you can’t send it to a web page written in php or a server in Java because there is no implementation of those new « flash 10 features (Vector, Dictionary,…)» in the flex framework. The thing you can do is use an Array instead of a vector, and enjoy the conversion in the Java Hash Map server sie. This is done because of the « sparse possibility of the array » (read my Tamarin Array Analysis). [...]

This is an excellent article and a real eye-opener too. It’s inspired me to write an article elaborating on the subject. It’ll be available tomorrow (Monday) on my site here: http://jacksondunstan.com/articles/529

Thanks for the article and the blog. Although you’ve just begun, you already have three killer articles. Keep up the great work!

Of course it does; I had misread the article. Thanks for clarifying that!

try the same thing but stop at index=1
while (–-i > 1)

There should be no or almost no difference. maybee the object will be a bit faster.

the “twice as fast” is due to the checkForSparseToDenseConversion wich is REALLY slow for a backward array!
