entication code .. Visit visit = (Visit) getVisit(); visit.setAuthenticated(true); if (_callback != null) { _callback.performCallback(cycle); } } } @version $Id: PageCallback.java 243791 2004-02-19 17:38:13Z hlship $ @author Howard Lewis Ship @since 0.2.9
org.apache.tapestry5.PageCallback
A way of capturing the name of a page and the page activation context so that, at a future date, the page can be invoked with that data. This kind of callback is very useful when creating more complicated workflows, where access to a page is "interrupted" with some operation before returning (via a callback) to the original flow.
Since the callback is serializable, it can be stored in the session. @since 5.2.0
