Interface IBreadCrumbParticipant

All Superinterfaces:
org.apache.wicket.util.io.IClusterable, Serializable
All Known Implementing Classes:
BreadCrumbPanel, BreadCrumbParticipantDelegate
public interface IBreadCrumbParticipant extends org.apache.wicket.util.io.IClusterable
Bread crumb participants function as proxies for components that are part of a bread crumb hierarchy. An example of a bread crumb is: 
     Home > Products & Solutions > Hardware > Desktop Systems
In a panel based implementation, Home, Products & Solutions etc would be separate panels that all are bread crumb participants: for instance the Home participant's title would return 'Home', and the component would be the corresponding panel.
