About types of methods and functions
Functions that belong to a class are called the methods of that class. There are several types of
functions that you can use in your applications, including built-in functions, named and user-
defined functions, anonymous functions, callback functions, constructor functions, and
function literals. The following sections contain information on how to define these
functions.
You can also write functions in an ActionScript class file. You use these functions as methods
in your scripts. In the following example, the Person class displays a constructor method, class
methods, instance methods, and accessor methods (getters and setters). The comments in this
code sample show where these methods occur in the code.

“Open the starter document” on page 213).
