Examples of org.apache.wicket.Page

org.apache.wicket.Page
Abstract base class for pages. As a {@link MarkupContainer} subclass, a Page can contain acomponent hierarchy and markup in some markup language such as HTML. Users of the framework should not attempt to subclass Page directly. Instead they should subclass a subclass of Page that is appropriate to the markup type they are using, such as {@link WebPage} (for HTML markup).
Page has the following differences to {@link Component}s main concepts:
- Identity - Page numerical identifiers start at 0 for each {@link Session} andincrement for each new page. This numerical identifier is used as the component identifier accessible via {@link #getId()}.
- Construction - When a page is constructed, it is automatically registerd with the application's {@link IPageManager}.
  Pages can be constructed with any constructor like any other component, but if you wish to link to a Page using a URL that is "bookmarkable" (which implies that the URL will not have any session information encoded in it, and that you can call this page directly without having a session first directly from your browser), you need to implement your Page with a no-arg constructor or with a constructor that accepts a {@link PageParameters} argument (which wraps anyquery string parameters for a request). In case the page has both constructors, the constructor with PageParameters will be used.
- Versioning - Pages support the browser's back button when versioning is enabled via {@link #setVersioned(boolean)}. By default all pages are versioned if not configured differently in {@link IPageSettings#setVersionPagesByDefault(boolean)}
