Class ViewList

java.lang.Object
  becker.util.ViewList

All Implemented Interfaces:

IModel

public class ViewList
extends Object
implements IModel

An instance of ViewList is usually used by a class implementing the model part of a model-view-controller to store its list of views. Each time the object's state changes, it should call updateAllViews. This, in turn, calls the updateView method for each of the views stored in the list.
