      aima.gui.framework.AgentAppModel

Direct Known Subclasses:

MapAgentModel, VacuumAppDemo.VacuumModel

public class AgentAppModel
extends BasicEnvironmentView

Facade hiding application specific design decisions from the AgentAppFrame. Subclasses should add methods to access informations about the environment's and the agent's state. Note that any data shown by an agent view must be provided by a corresponding model. The model-view-controller architecture forbids any component of the application except the controller to directly access the view components and it forbids the views to access information without consulting the model.
