Question

Is it possible to wrap a variable-length-arguments function in Actionscript?

I tried

    private function getString (name:String, ...args):String {
        return var_arg_function(name,args);
    }

but it didn’t work since sprintf was called with just 1 extra argument, i.e. the Array args.

I’m not aware of sprintf in AS3, but perhaps you’re using a custom function… Try using Function.apply. I haven’t tested this, but something like:

private function getString(name:String, ...args):String {
     return sprintf.apply(this, [xxx.getString(name)].concat(args));
}
