[flexcoders] re-passing variable arguments?

2008-12-29 Thread toofah_gm 
I have a method that accepts variable arguments like this:

public function doSomethingThenContinue(continueFunction:Function, 
...args)
{
   // execute some code that does important stuff

   // call the continue function now that we are done passing the 
original args to that function
   continueFunction(args);
}

Is it possible to pass the variable arguments on to the generic 
continueFunction in this manner?  I don't really want the args to be 
passed in a single Array, but want to call the continueFunction with 
the arguments split out like this dynamically 
continueFunction(args[0], args[1], etc.) depending on how many were 
passed in and depending on how many parameters the continueFunction 
accepts.

Is this possible to do somehow?

Thanks,

Gary

Yes, through the magic of higher-order functions:

  continueFunction.apply(this, args);

What you're after is usually called a splat. It's not supported quite so
explicitly in AS3, but to do what you're after just use Function.apply(). So
in your case, it'd be:

continueFunction.apply(this, args);

Try continueFunction.apply(args);
