The ActionScript 2.0 compiler can resolve static member references within class definitions. In
the previous example, if you don't specify the class name for the

However, for optimal readability of your code, it is recommended that you always use explicit
references in your code, as shown in the previous example, to easily identify where the definition
of a static member resides.

Implicit getter/setter methods

Object-oriented programming practice discourages direct access to properties within a class.
Classes typically define getter methods that provide read access and setter methods that provide
write access to a given property. For example, imagine a class that contains a property called
:
userName
var userName:String;
Instead of allowing instances of the class to directly access this property (
, for example), the class might have two methods,
"Jody"
would be implemented as shown in the following example:
class LoginClass {
private var userName:String;
function LoginClass(name:String) {
this.userName = name;
}
function getUserName():String {
return this.userName;
}
function setUserName(name:String):Void {
this.userName = name;
}
}
As you can see,
getUserName
value of
userName
then use the following syntax to get or set the
var obj:LoginClass = new LoginClass("RickyM");
// calling "get" method
var name = obj.getUserName();
trace(name);
// calling "set" method
obj.setUserName("EnriqueI");
trace(obj.getUserName());
, the ActionScript 2.0 compiler ascertains that the reference
widgetCount
and correctly exports that property. Similarly, if you referred
SubWidget.widgetCount
Widget.widgetCount
returns the current value of
to the string parameter passed to the method. An instance of the class would

because is a subclass of the
