 wicket.markup.html.link.PageLink
| PageLink | | public class PageLink extends Link (Code) | | Links to a given page via an object implementing the IPageLink delayed
linking interface. PageLinks can be constructed directly with an IPageLink
interface or with a Page Class object. In the latter case, an IPageLink
implementation is provided which constructs a Page of the given class when
the link is clicked. A default no-args constructor must be available in this
case or a WicketRuntimeException will be thrown when Wicket fails to
instantiate the class.
