Interface PageView

All Superinterfaces:
ChildView, MarkupBasedView, NavigableView, ParentView, Serializable, ThemedMarkupBasedView, View

public interface PageView
extends ParentView, NavigableView, ThemedMarkupBasedView

"Views" are deep copy immutable objects. Unlike "Definitions" and "Instances" Views cannot be modified by the developer. A Instance or a Definition however can always be obtained from the view. The persistence APIs provides course grain and fine grain getters but only fine grain setters. If you are interested in an object and all its children then retrieve the View, if you are only interested in the immediate object and don't care about its children then retrieve the Definition.

The page view represents a page and all its contents. Pages are used to display child Portlets and child Books in a specific layout in a browser. A common term/interface used to represent things that can be placed on a page is "Placeable". So both Book and Portlet extend Placeable. There is no theoretical limit to the number of placeables a page may contain.
