Oh yeah,

I will definitly be looking forward to that AS3 Optimization session ;-)

Ok,

Thanks,

FYI I wrote it this way so I could break down the road. I see what you are saying now.

Now that I see the light, if I need to break, just use an if statement in the loop.

You know, some times I feel stupid for trying to do things that in the end look a little funny :)

Ironically, I was trying to solve a future problem and I created a future problem.

Thanks for the time Gordon. :)

You have six methods calls being pushed
onto the stack for each of 600 files, so you are at 3600 stack frames.

 

You need to write your algorithm to loop
rather than recurse.

So,

I need to slim what I call then? I am no where near 4000 recursions on this. 

Do you have any advice for me? I wrote this documenter in Flex to really test
the Flash player, I am getting good feelings but, this I just need to work
right now and then when I refactor it won't be a problem.

So a stack is like a method call chain, so really I need to slim the whole
algorithm and not use dispatchEvent().

Maybe me using dispatchEvent() is adding on the recursions I am not seeing. 

Peace, Mike

I got more info from the
AS3 team... The Player's stack limit is 128K and can't be changed. When a
method calls another method, a stack frame gets created which requires 4 bytes
for its size, 4 bytes for the return address, 4 bytes for each parameter, and 4
bytes for each local variable. So if a typical function has 2 parameters and 4
local variables, you could have about 4000 recursive metthod calls.

A StackOverflowError does
not necessarily involve an Array. It generally is an indicator of infinite (or
at last overly deep) recursion, such as where method A calls method B and
method B calls method A, over and over. In your stack trace, it looks like
File/analyzeNextFile() is being called recursively rather than sequentially.

Hi,

I am getting a #1023 statckoverflow error on lines that have nothing to do with
an array.

Is this a memory error? Like the player is out of memory. It's happening in a
VERY intensive proccessing loop.

The docs say talk to Adobe, if the swf is not corrupt.

Thoughts?

Peace, Mike
