IBreadCrumbParticipant (Wicket Extensions 9.22.0 API)

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.
