Hello!

So I am pretty familiar with memory management in Java, C and C++; however, in flash what constructs are there for memory management? I assume flash has a sort of virtual machine like java, and I have been assuming that things get garbage collected when they are set to null. I am not sure if this is actually the case though. Also is there a way to force garbage collection in Flash? Any other tips?

Thanks

I've been looking for a solution to this for years, but nothing is conclusively documented. There are many Shoutcast Flash players out there (e.g. radio.de) so I know it's possible.
