FLASH® LITE™ 2.x - Adobe Help and Support

Book.prototype.getTitle = function():String {
return "Catcher in the Rye";
};
Book.prototype.addProperty("bookcount", Book.prototype.getQuantity,
Book.prototype.setQuantity);
Book.prototype.addProperty("bookname", Book.prototype.getTitle, null);
var myBook = new Book();
myBook.bookcount = 5;
trace("You ordered "+myBook.bookcount+" copies of "+myBook.bookname);
The following example shows how to use the implicit getter and setter functions available in
ActionScript 2.0. Rather than defining the Book function and editing Book.prototype, you
define the Book class in an external file named Book.as. The following code must be in a
separate external file named Book.as that contains only this class definition and resides within
the Flash application's classpath:
class Book {
var books:Number;
function set bookcount(numBooks:Number):Void {
this.books = numBooks;
}
function get bookcount():Number {
return this.books;
}
function get bookname():String {
return "Catcher in the Rye";
}
}
The following code can then be placed in a FLA file and will function the same way as it does
in the previous examples:
var myBook:Book = new Book();
myBook.bookcount = 5;
trace("You ordered "+myBook.bookcount+" copies of "+myBook.bookname);
