Howto examine loaded SWF file classes
I got into an issue how to problematically examine all classes loaded into my SWF file. After some search it occurred that unfortunately there is not an easy way yet. Good news is that I found two libraries available that can do what I was looking for, below you can find links:

BTW: I will be lobbying my colleagues at Adobe to add this in the future releases 
this (among many others) can also be done with this swf reading class http://swfutils.riaforge.org/

Mateusz, thank you for pointing me to it, I will give it a try soon with a project that I’m just starting.

swfutil’s getDefinitions method returns an array of linkaged classes (using just SymbolClass tag), not all classes, which available in swf. Same simple method used in SWFExplorer too. But, getDefinitionNames parses the DoABC tag and returns all class names, not only linked.
I’m planning to add “onlyLinked” feature to getDefinitionNames method, if you want to use only linked classes.
etc
