ANE function parameters display as arg0, arg1, etc. how do I fix this?

Question

I am creating an ANE and all my functions that take parameters show them as arg0, arg1, arg2, etc..
for example:
ShowAlert(arg0:String, arg1:String, arg2:String = "Ok", arg3:Array = null)
when it should be
ShowAlert(title:String, message:String, defaultButtonText:String = "Ok", additionalButtons:Array = null)
I did some searching and the only thing I was able to find was this:
By default, these are defined as arg0 and arg1, but you can give them more descriptive names. Change the call() function definition to look like this:
public FREObject call(FREContext context, FREObject[] passedArgs)
from http://www.adobe.com/devnet/air/articles/developing-native-extensions-air.html
hrm..
I assume it's using flex (as pretty much everyone else is these days - I should get around to learning that) but I am using Flash Pro.
Anyway, I don't really understand what he meant, so I started reading the rest of the document and I saw this line:
Set the superclass to com.adobe.fre.FREContext.
Hrm...
Does this mean I am supposed my ANE is supposed to extend that? Right now, it's extending EventDispatcher.
Regardless, can someone clarrify what he means, or what I am supposed to do to get my parameters appearing correctly?

Answer 1

It does look like you want to extend FREContext.
