Classes extended from ActionController:

Located in File: Program_Root/ActionController.php

The ActionController class represents the controller in the
 Model-View-Controller (MVC) design pattern. The ActionController receives
 and processes all requests that change the state of the application.

 Generally, a "Model2" application is architected as follows:
 

 
The user interface will generally be created with either PHP pages,
 which will not themselves contain any business logic. These pages represent
 the "view" component of an MVC architecture.
 
Forms and hyperlinks in the user interface that require business logic
 to be executed will be submitted to a request URI that is mapped to the
 ActionController. The ActionController receives and processes all requests
 that change the state of a user's interaction with the application. This
 component represents the "controller" component of an MVC architecture.
 
The ActionController will select and invoke an Action class to perform
 the requested business logic.
 
The Action classes will manipulate the state of the application's
 interaction with the user, typically by creating or modifying classes that
 are stored as session attributes. Such classes represent the "model"
 component of an MVC architecture.
 
Instead of producing the next page of the user interface directly,
 Action classes will forward control to an appropriate PHP page to produce
 the next page of the user interface.
 
 The standard version of ActionController implements the following logic for
 each incoming HTTP request. You can override some or all of this
 functionality by subclassing this class and implementing your own version of
 the processing.
 

 
Identify, from the incoming request URI, the substring that will be used
 to select an Action procedure.
 
Use this substring to map to the class name of the corresponding Action
 class (a subclass of the Action class).
 
If this is the first request for a particular Action class, instantiate
 an instance of that class and cache it for future use.
 
Optionally populate the properties of an ActionForm class associated
 with this ActionMapping and cache it for future use.
 
Call the perform() method of this Action class. Passing in the mapping
 and the request that were passed to the ActionController by the bootstrap.
 
 

 The standard version of ActionController is configured based on the
 following initialization parameters, which you will specify in the options
 for your application. Subclasses that specialize this ActionController are
 free to define additional initialization parameters.
