public interface IPageMapEntry
- extends IClusterable
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).
