Examples of PageProvider

org.apache.wicket.core.request.handler.PageProvider

Provides page instance for request handlers. Each of the constructors has just enough information to get existing or create new page instance. Requesting or creating page instance is deferred until {@link #getPageInstance()} is called.

Purpose of this class is to reduce complexity of both {@link IRequestMapper}s and {@link IRequestHandler}s. {@link IRequestMapper} examines the URL, gathers all relevantinformation about the page in the URL (combination of page id, page class, page parameters and render count), creates {@link PageProvider} object and creates a {@link IRequestHandler} instancethat can use the {@link PageProvider} to access the page.

Apart from simplifying {@link IRequestMapper}s and {@link IRequestHandler}s {@link PageProvider}also helps performance because creating or obtaining page from {@link IPageManager} is delayeduntil the {@link IRequestHandler} actually requires the page. @author Matej Knopp
