Finding methods / properties of a swf object

I have a swf object embedded in a webpage. Without having access to the source code of the swf file, how can I find the methods / properties that were exposed?

For instance...

alert(document.getElementById('swfObject').id);

      

        
        
        
      

    

... returns the "swfObject" popup. And this...

document.getElementById('swfObject').someMethod();

      

        
        
        
      

    

... executes someMethod.

Thanks.
