Interface IPageMapEntry

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

AbstractPageMapEntry, AccessDeniedPage, AccessDeniedPortletPage, BrowserInfoPage, DummyHomePage, DummyPanelPage, ExceptionErrorPage, ExceptionErrorPortletPage, InternalErrorPage, InternalErrorPortletPage, Page, PageExpiredErrorPage, PageExpiredPortletPage, PopupCloseLink.ClosePopupPage, PortletPage, RedirectPage, WebPage

public interface IPageMapEntry
extends java.io.Serializable

Some source which produces a page. Page implements IPageMapEntry by simply returning "this", but other implementations are possible as well, allowing users to create IPageMapEntry implementations that reconstruct full blown Page objects from a limited set of data (for example, a details page from an id). The advantage of doing this is that you can save session memory (by trading off against the processing power required to reconstruct the page).
