The execution of the session design pattern in an online application could look something like this: The Session class in this example is built as a singleton and has methods for logging in and out, verifying the state of verification, and obtaining the user. The class has a static way for locating the sole instance as well as a private function Object() { [native code] } that makes sure no more than one instance of the class can be made. In this manner, the user's login state can be checked, their user object can be retrieved, and their session can be maintained throughout the application by accessing the session object from anywhere in the application.
