Re: Re: [Flashcoders] Abstract classes in AS3?
For compile time checks, just use a private constructor. As
ActionScript allows one to access a private (not really private) super
constructor in a subclass this works perfectly. At least this is what
I do when I need an Abstract class in ActionScript.
E.G.
class com.tomsnyder.fasttmath2.studentclient.activities.tasks.AbstractTask
{
//private constructor to discourage instantiation
private function AbstractTask() {
//initialization code here
}
}
Now there's no way to instantiate it, and the compiler will bitch
about it if you try.
I hope that helps.

AS3 doesn't support private constructors.

Re: Re: [Flashcoders] Abstract classes in AS3?
Hello ;)
In AS3 the private keyword it's removed !! ;) You can't use this keyword for
your constructor :)
EKA+ :)
