please check ur code..

Unfortunately, I wrote the examples in this article using one of the early betas of Flex 2, when multiple classes could be defined in a single package in a single .as file, with the restriction that only one of the classes could be public.

Since then, the rule has been changed, and as you’ve noted, the Flex 2 compiler now only allows one class in the package block in a .as file, and no class can be declared private or protected. However, as you’ve noted, you can still define other classes in a .as file, outside of the package, which has the same net result as the “private” classes in these examples — those classes are accessible to classes defined in the same .as file, but not to any other class.

Interestingly, it appears that the “one class per package block” restriction is a Flex compiler restriction rather than an ActionScript restriction — see this article (“Multiple AS3 Classes in One File”) for more details on how to do that. However, all the classes defined in the package block must still be public or internal.

I just spent like an hour on Flex Builder trying to get this example compiling with no luck

“speaking pets in ActionScript 3”

I just wanted to paste that class and get it working that’s all. All I am trying to do is to have multiple classes within one file under one package.

The “speaking pets in ActionScript 3”

produces an error
: The private attribute may be used only on class property definitions

I was able to get multiple classes working but if only one class stayes inside the package and the rest are outside.

please let me know, if this can be done

I would really appreciate a clear example

Thank you

Kind Regards,

Any notion on when ASUnit.org will have this taken care of? Would really like to begin trying some unit tests, but must use Flash 8.

Thanks! (Great article, by the way!)

In AS2 there was something called __resolve which works somewhat like what you describe — basically you define a method named __resolve in your class, and any time code calls a method or property which isn’t explicity defined in the class, the call gets passed to the __resolve method. (Technically __resolve is a property of the Object class, so you are overriding that property when you define the method in your class).

Details:
__resolve documentation

Of course, you asked about AS3, so that’s really all historical background information, nothing more. In AS3 the __resolve approach is no longer available. Instead, there is a new class, the flash.utils.Proxy class, which can be used to provide the same functionality. It is one of the peices of what they’re calling the “Reflection API” in ActionScript 3. Admittedly I haven’t used the Proxy class yet, so I can’t give details on how it works, but the class has methods with names like “callProperty”, “getProperty”, “setProperty”, etc., so it doesn’t take too much imagination to at least see what some of the possibilities are.

I hope this is helpful. Sometime soon I will be doing some work with reflection in ActionScript 3, and maybe when I’ve worked with it some I will write something up about it.
