org.scopemvc.view.servlet
Class ServletView  

java.lang.Object
  org.scopemvc.view.servlet.ServletView

All Implemented Interfaces:

org.scopemvc.core.View

---

public class ServletView

extends java.lang.Object

implements org.scopemvc.core.View

A container View to aggregate a set of Pages the allows the currently visible Page to be set.

In a servlet application, a Controller's View must 'contain' all the possible pages that the user could be interacting with because the user is free to hit the browser's forward and back buttons, use history or bookmarks etc. This "View" therefore acts as a simple container for other Views (Pages) that represent the actual interfaces that the user interacts with. It forwards any setController(org.scopemvc.core.Controller) 55 and setBoundModel(java.lang.Object) 55 calls to all children.

A Controller in a web application must create an instance of ServletView to put all its possible Pages into using addPage(org.scopemvc.view.servlet.Page) 55 . The Controller then setView() establishes the container as the Controller's View. To determine the Page that is shown to the user on showView, call setVisible(java.lang.String) 55 with the Page ID.
