Comments on: Sneaky Flex trick to get the name of any calling functions http://dougmccune.com/blog/2008/02/21/sneaky-flex-trick-to-get-the-name-of-any-calling-functions/ A blog about Adobe Flex Thu, 09 Feb 2012 13:51:00 +0000 hourly 1 http://wordpress.org/?v=abc By: Arodicus http://dougmccune.com/blog/2008/02/21/sneaky-flex-trick-to-get-the-name-of-any-calling-functions/comment-page-1/#comment-209386 Arodicus Thu, 06 May 2010 22:53:01 +0000 http://dougmccune.com/blog/2008/02/21/sneaky-flex-trick-to-get-the-name-of-any-calling-functions/#comment-209386 Great tip! Really saved my butt! Note: Alan Shaw's example is great but has a flaw: If a class or method contains the letters "at" you'll get bogus results. Corrected version: public function functionName():String { var result:String = ""; try { var stack:String = new Error().getStackTrace(); var stackArray:Array = stack.split("\n\tat"); var subStack:String = stackArray[3]; // because this is the 3rd function away from the caller... we want the caller var j:int = subStack.indexOf("()"); result = subStack.substring(0, j+2); } catch(e) {} return result; } Great tip! Really saved my butt!

Note: Alan Shaw’s example is great but has a flaw: If a class or method contains the letters “at” you’ll get bogus results.

Corrected version:

public function functionName():String
{
var result:String = “”;
try {
var stack:String = new Error().getStackTrace();
var stackArray:Array = stack.split(“\n\tat”);
var subStack:String = stackArray[3]; // because this is the 3rd function away from the caller… we want the caller
var j:int = subStack.indexOf(“()”);
result = subStack.substring(0, j+2);

} catch(e) {}
return result;
}

What's also nice is that if you're on a breakpoint, you can click on any of the items in the stack in that panel to switch to that object's context, ie: be able to see its variables and such. Very handy stuff. Keep in mind that if you’re running the debugger, you can see the stack trace at any time within the Debug panel.

I wasn't aware of the verbose-stacktraces Theo blogged about. I guess maybe the reason they left that information in the release swf by default is to enable developers logging their apps. Hmm..and maybe not. Cheers, Almog Kurtser. Hi,

Is that a new version of flexSpy, or just one you've hacked together. I'll like the source if you're making it available. cheers glenn Hi,

All I know is that in my blog post I tried embedding a version of the app that I exported as a release build with FB 3 B3 and the getStackTrace() stuff didn't work when I viewed it on the web page (maybe my player didn't know it was supposd to be in debug mode?). So then I just re-uploaded the version that was the normal debug swf and it all worked fine for me. @Alan, hmm, interesting.
