Ok, if your class is a component, and has been added to the display list (as a child of the main class), you can reference a public variable in the parent class with either outerDocument.myVariable or parentDocument.myVariable. Personally, I don't like this kind of dependency, and recommend creating a getter/setter variable in the class and set it after the class is instantiated and, if needed, when the main variable is changed. A getter/setter is recommended for the top level variable as well. This way your class can initialize it's own state, if desired have it's state changed by the parent, and become re-usable; without depending on the parent.
