org.apache.wicket.session.pagemap.IPageMapEntry
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). @see org.apache.wicket.session.pagemap.AbstractPageMapEntry @author Jonathan Locke
