Flex swf file: how to inspect the method exposed?

In every language there are a lot of tool to inspect the interface exposed by the compiled file, then what is the best tool for Flex swf file? I am debugging my code but the invoke always failed, I am writing my callee like bel开发者_运维问答ow in my mcml file:

            public function playVideo():void
            {
                svid.play();
                return;
            }

And in another mcml I am using SWFLoader to load it and call it, but it always failed.

Thanks.

Do you mean runtime introspection, or introspection while you're developing?

For runtime introspection, I've found as3-reflect very helpful.

For developing, though… I just use FlexBuilder's autocompletion. I'd be interested to learn about a better way, though.
