Object-Oriented ActionScript

• Polymorphism
• Inheritance
• Encapsulation

Classes and Interfaces

ActionScript requires classes/interfaces to be declared in a package and the explicit import of used classes/interfaces that are not in the same package.

Class Definition

ActionScript class definition:

package packageName
{
   import another.packageName.*;
   
   public class ClassName extends SuperClassName implements InterfaceName
   {
      public ClassName()
      {
         // constructor
      }
   }
}

ActionScript also supports dynamic classes.

Interface Definition

ActionScript interface definition:

package packageName
{
   public interface InterfaceName extends AnotherInterface
   {
      // public not necessary (and not allowed)
      function methodName():void;
   }
}
