IActionController (ITF)

INTERFACE IActionController EXTENDS __SYSTEM.IQueryInterface

The behaviour of an action provider can mostly be influenced by an action controller. An action controller implements the IActionController interface and can be connected to a BehaviourModel instance via the ActionController property of the IBehaviourModel interface. If an action controller is connected to a BehaviourModel instance, the state machine will call the methods of the action controller instead of the methods of the action provider. The methods of the action controller will be called from the state machine parameterized with the related action provider method. So the action controller can encapsulate the original methods of the action controller and so create some specific modifications of their behaviour.
