Examples of org.apache.wicket.request.cycle.RequestCycle

org.apache.wicket.request.cycle.RequestCycle
{@link RequestCycle} consists of two steps:
1. Resolve request handler
2. Execute request handler
During {@link IRequestHandler} execution the handler can schedule another {@link IRequestHandler}to run after it is done, or replace all {@link IRequestHandler}s on stack with another {@link IRequestHandler}. @see #scheduleRequestHandlerAfterCurrent(IRequestHandler) @see #replaceAllRequestHandlers(IRequestHandler) @author Matej Knopp @author igor.vaynberg
